Lukka, Coppercoat Outcast

[+1]: Exile the top three cards of your library. Creature cards exiled this way gain "You may cast this card from exile as long as you control a Lukka planeswalker." [-2]: Exile target creature you control, then reveal cards from the top of your library until you reveal a creature card with higher converted mana cost. Put that card onto the battlefield and the rest on the bottom of your library in a random order. [-7]: Each creature you control deals damage equal to its power to each opponent.
