Chromium

Greetings to Who Want to See Reality Without Grand Illusions,
Chromium is really Green, White, and Blue... and Black... Plus he can firebreathe in those four colors. Rampage is really those creatures that attack with it, plus those who defend against it. And one other point, there is not really and upkeep cost. Chromium becomes nearly invincible when paying the four colors during upkeep for the duration or the turn, otherwise he is normal. He is not buried if you don't pay. He is not an extortionist, he is a Dragon Legend Elder... So, why don't you all print the big plasic, multi-layered versions of the cards which cover every extingincy, and get rid of any detrimental illusion...
The King of Castle Noq

He is a god of wicker baskets and especially truth when black mana is the foreground for the elaborate wanderings of your enemies. Keep him up on all four colors and when another turn comes into play, throw her at your opponents mana pool and witness the splash of ancient titans. And if your enemy tries to disengage from the operations, just apply the third law of motion and watch him cry as the whole house of cards falls down around him, just as Chaos theory predicted it would almost 15 years ago! That one is out of the park!
