Nissa, Vital Force 3GG Planeswalker - Nissa +1: Untap target land you control. Until your next turn, it becomes a 5/5 Elemental creature with haste. It's still a land. -3: Return target permanent card from your graveyard to hand. -6: You get an emblem with "Whenever a land enters the battlefield under your control, you may draw a card." 5

Not sure what to think of this one. She protects herself and can ult the turn after you play her for an emblem that's pretty good, but is it worth 5 mana and opening up one of your lands for a removal spell?
