Lukka, Coppercoat Outcast
Legendary Planeswalker — Lukka
+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 mana value. 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.
