Companion -- Your starting deck contains only cards with even mana values. (If ~this~ is your chosen companion, you may put it into your hand from outside the game for {3} as a sorcery.)
When ~this~ enters, 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.
