Legendary Creature - Demon Kraken 

6/6 

Companion - Your starting deck contains only cards with even converted mana costs. (If this card is your chosen companion, you may cast it once from outside the game.) // When Gyruda, Doom of Depths enters the battlefield, each player puts the top four cards of the library into their graveyard. Put a creature card with an even converted mana cost from among those cards onto the battlefield under your control.
