Zalaras the Indomitable

This is one of the tribal leaders in a tribal-heavy block called Hesperia Block, where Dragons are seekers of knowledge and are highly accomplished magicians.

And they're quite arrogant too.

Kruss, Gorger of Worlds

Legendary Creature - Dragon Beast
5/4
Flying
, sacrifice a land: Kruss, Gorger of Worlds deals 3 damage to target creature or player. Then, put a +1/+1 counter on it.
When Kruss, Gorger of Worlds leaves the battlefield, each opponent sacrfices X lands, where X is Kruss, Gorger of Worlds's power.
His judgement is dark, burning, and climactic.

Kruss is endlessly roaming around the plane of Colfbrand, terrorizing the countryside, incinerating the villages and livestock. He does everything a classic fantasy dragon should do (except hoard treasure). He wants nothing less than the total destruction of the wretched species that is man.

Oh, wow, I just realized that my entry is supposed to have do something else.

Tann'altheia the Crashing Wave
Legendary Creature - Leviathan Elemental {M}
Trample
Whenever empties from your mana pool, tap target permanent.
Whenever Tann'altheia the Crashing Wave deals combat damage to a player, return that many tapped permanents that player controls to its owner's hand.
10/10
No ones knows what it is. No one even knows that it is sentient. But all know that when the tides of autumn reach land, the coast disappears.

3ed times the charm, right Sewn-Eye.

Here's my take on this challenge

So does `empty from your mana pool` when you use said mana to cast a spell? Either way, nice card Sewn-Eye; you should get bonus points for persistance too.

Klazzerdrix
Legendary Creature -- Rabbit Beast (R)
Affinity for Rabbits, double strike
Whenever a Rabbit creature attacks, up to two target creatures can't block this turn.
4/4

You know, with all the dragons in this thread, I think Zalaras already has a bunch of team-mates.

Also, a different version from the original.

Zalaras the Indomitable
Legendary Creature- Dragon Wizard
Flying, haste
All other Dragons get +1/+1.
When Zalaras enters the battlefield, untap all Dragons you control. These Dragons gain haste until end of turn.
: Zalaras gets +1/+0 until end of turn.

(@ Jrzman: Just judge whichever version of Zalaras is better.)

So you can actually have two submissions and just use the better one. Actually, you have to say which one he should judge, since it would be unfair otherwise.

You should probably address the proper judge too, seeing as A Tactical Waffle (not jrzman) will be judging.

@ Nikeiya & Vinyacoire: Alright, then. My bad.

@ ATW: Just judge the second version of Zalaras.

Athroxia, Time Devourer
Legendary Creature - Ooze Mutant (M)
Trample
When ~ enters the battlefield, exile all cards in your library and another permanents you control. For each card or permanent exiled this way, ~ gets +1/+1 until end of turn.
7/7

No haste? Intentional!

Sanity Consumer
Legendary Creature - Demon
When you cast ~, you may put any number of cards from your library into your graveyard.
~ enters the battlefield with a +1/+1 counter on it for each card put into the graveyard this way.
-10/-10

Yes, these are minus. Smallest P+T on a magic card ever. Still a fatty.

Brashir of the Forward Guard
Legendary Creature - Human Soldier {M}
Haste, vigilance, first strike.
Brashir of the Forward Guard can block any number of creatures.
For each creature blocking Brashir, put two +1/+1 counters on him.
, remove a +1/+1 counter: Brashir deals 1 damage to target creature.
He charges forward with no sense of security for himself, only for us. And yet his strength still grows. It amazes many in this force even today.
-Gromir, first class recruit.
3/3

He just grows and grows as he blocks more and more. And then he can take his growth and vent it out as rage.

I think I will judge a bit early. I will now be judging on Thursday.

I'm actually not sure. My original intent to have it just be from letting mana empty from your mana pool between phases, and then I thought, "Maybe it'll apply to when you use mana to cast spells..." And now I sit here and wonder.

Scorn-Eyes the Yoremaster

Inspired by Yore-Tiller Nephilim, the nongreen Nephilim.

EDIT: Second thoughts on where the should go.

Contest is closed, judging now.

Il-Fingle, the City -
Legendary Creature - Beast
When Il-Fingle enters the battlefield, sacrifice three lands or Il-Fingle.
Defender
: Add to your mana pool.
: Target creature you control gets +1/+1 until end of turn.
7/11

Let the judging start!

So we had HudsonWolf and Guitarweeps with 30. I'm going to give the win to my favorite of the two and that is....

Nice job, we awate your next challange.

EDIT: Oh, sorry picks, just a bit to late. I hope I didn't ninja you with my contest closed comment.

So many great entries. Also, for ElmdorMesdoram's entry - Vizzerdrix. Although, tbqh, I never really saw any flavor in that card either.

Congrats, Guitarweeps! Props for such a slick ability.

by 3 minutes! A combination of having difficulty fleshing it out and distractions at work Grats Mr Weeps.

I thought insatiable one would be just a little bit too powerful, especially in multiplayer, trust me to forget to check mana costs at the end of a card design. Still, I'm happy with the big tie for third with 29 points.

Congrats Guitarweeps! By the way, @ATW, it's an Ooze Mutant, it's mutation makes the Ooze beast-like, even by itself most Oozes are having devouring concept but yeah this card is too "I win" card and I respect of your word when you don't see Ooze and beast (not creature type) in common After all, I want to use a different creature type than other contestants

Could you rate my card too?
Please?

Wow thanks! I really liked how the card turned out so I am glad everyone liked it.

So now the next challenge is something I have wanted to post here anyways but the timing is ironic as there has been some recent controversy on this subject here lately... I want you to design a card that does do what a color can't do. There are some rules though:

1. It HAS to make sense mechanically and in flavor.
2. You cannot simply raise the CMC or rarity (not to be confused with appropriate balancing).
3. It does not have to be mono-colored but it has to do something that all colors it possesses does not do.
4. It cannot have anything to do with a color that has that effect aka no "if you control an Island" or "if was spent to cast this".

If I have confused anyone here are some examples:

Green does not get spot removal.
Wing Snare is a good example of how green can do it. Unyaro Bee Sting is a bad example since it is just a raise in CMC.

Red does not get card draw.
Browbeat is a great example of red getting around that.

White does not get counterspells.
Lapse of Certainty is a great example of how it can.

Hope that sets the stage. I will shoot for judging next Sat or Sun (my schedule is determined by my newborn). Let the games begin!

@ Smooth: Sorry, I missed you card. Here you go.

Challenge -10- Good job.
Balance -5- Way to good. You take out everything but a few cards that give you shroud and you win.
Beauty -10- I like it, I always liked demons that hurt you in some way.

Works well with cards like Anger and Wonder!

My bad, of course it should have been "from the top of your library" not "search your library for any number of cards".
Seems I kinda lacked concentration when I was posting that, the order of the mana symbols are wrong too...

nvmd, I'll do better next time.
Thanks for judging the card anyways!

March of Progress

Sorcery
Search your library for a land card, reveal it, and put it onto the battlefield. If it's basic, tap it.
"Someday, we shall replace all the wild things of this world with our own creations. For now, however, we shall rely on our own works and only use nature when necessary."
- Saldrath, master artificer

(Blue has poor mana acceleration, but loves nonbasic lands.)

Whiteflame
Creature - Elemental
: ~ gets +1/+0 until end of turn.
The brightest fires burn white.
2/4

(Black can't kill enchantments.)
Bound by Lineage
Sorcery {R}
Target opponent sacrifices a permanent with the same name as target card in his or her graveyard.
Creations, machinations, and pithy magicks all fall prey to their lineage of weakness.

Black doesn't have damage prevention. Darkness, Sewers of Estark and Demonic Torment are clearly off-color.
I stole flavor text from Deflection, it looked good in my card

Wicked Reversal
Instant (R)
The next time a source of your choice would deal damage to you this turn, prevent that damage. That source's controller loses life equal to the damage prevented this way.
The golden rule of revenge: Do unto others what they tried to do unto you.

Cost is high: 1C more than Reverse Damage. I assume 2 can be considered the difference between life loss and life gain (example: Mangara's Blessing and Lava Axe), and this card feels wrong at 3BB.

The Petrifying
Creature - Spirit Horror
Whenever a creature would be put into a graveyard from play, you may tap target creature.
2/2
Michael watched as the beast shredded his one remaining friend. The beast glared at him with its haunting eyes, indicating in no uncertain terms that he was next. He could do nothing but sit and stare in horror.

I think this might have been done before, but here you go...

Singulize
Sorcery
Target creature becomes a 0/0 with no abilities until end of turn.
Whoever said size doesn't matter, was probably really short.

So, I thought of many concepts as to what certain colors can't do and that many colors can do stuff that is outside their specialty; and of course, black can do anything if you pay the price (or life). But what about stealing your opponent's stuff? Blue's specialty for sure, but we've seen our fair share of it in red, certainly black, and even a bit in white; but green? May I present:

Pack Intimidation
Enchantment
Tap X untapped creatures you control: Gain control of target creature with power less than X.

Magus of the Pool
Creature - Human Wizard
: Add to your mana pool one mana of any type that a land you control could produce.
Her mirror reflects the present that could have been.
1/3

The precedent? Unbender Tine and untapping lands!

Living Tidalwave
Creature - Elemental (U)
Haste
Whenever you control no untapped islands, sacrifice ~.
2/2

green can't destroy lands

Fungal Reclamation
Sorcery
Destroy target tapped, nonbasic land.The, search your library for a basic land, reveal it, then put it in your hand.

@ Teljilad: Acidic Slime, Creeping Mold, Deus of Calamity, Drain the Well, Feast of Worms, Ice Storm, Marshdrinker Giant, Mwonvuli Acid-Moss, Reap and Sow, Roiling Spoil

Soryy Teljilad, but green can destroy lands. And it does it a lot.

Red can't destroy creatures (other than by bringing them to a horrible death by burning alive) and enchantments, and blue can't destroy any permanents (with rare exceptions like Pongify or Frozen Solid, and when it does the phrase "It jumps though a loop or two" is the understatement of the day).

This:

Chrome and Crush
Sorcery
Kicker
Target permanent becomes an artifact in addition to its other types. (This effect lasts indefinitely.)
If Chrome and Crush was kicked, destroy target permanent if it’s an artifact.
“I wonder what it would look like if...
Oh my god, kill it, KILL IT!”

It's basically Memnarchs first ability with a simple Shatter, with a different wording to make it work.
Memnarch + Shatter = Vindicate

Sacred Ritual -
Sorcery
At the beginning of your next main phase add to your mana pool for each Cleric you control.

I don't think I need to say any more!

Swarm of Gnats -
Instant
Target creature gets -X/-0 until end of turn.
Draw a card.
In Llanowar, even the smallest distraction can be dangerous.

This is traditionally a blue ability, and green doesn't have much in the way of tricks or dealing with creatures (other than fogs).

Black doesn't have Clone ability, right?

Face of Impostor
Instant (R)
Put a token that’s a copy of target creature spell an opponent controls onto the battlefield.
"Beware the shadows of yourself."
-Sign of Dragnia Castle

In black, Clone ability shows as an impostor-generating. Isn't it interesting?

Black sorta has a clone ability. Nemesis Trap

Okay, but it's rarely appeared and it's also a form of removal, when my card isn't. I edit my card so it won't be a dead card at any time

Face of Impostor (1BB)
Instant (R)
Put a token that’s a copy of target creature spell an opponent controls onto the battlefield.
Cycing
"Beware the shadows of yourself."
-Sign of Dragnia Castle

Bryphian Timeslayer
Creature - Elemental Wizard {U}
, : When target creature spell resolves, ~ deals 2 damage to that creature.
1/2

I have absolutely no idea how to word this.

Destructive Research
Instant
Flip a coin. If you win the flip destroy target artifact. If you lose the flip destroy target enchantment.
Draw a card.
I'm pretty sure blue rarely gets any of these effects (other than the cantrip obviously)

Holy crap. Nice card Lord Joakim; way to twist a red ability onto a blue card.
Also, I think your wording works perfectly.
