Gyruda, Doom of Depths

Companion—Your starting deck contains only
cards with even mana values. (If this card is your
chosen companion, you may put it into your
hand from outside the game for {3} as a sorcery.)
When Gyruda enters the battlefield, each
player mills four cards. Put a creature card with
an even mana value from among the milled
cards onto the battlefield under your control.
