A 4/4 for four mana, Gisa states that when a creature under an opponent's control would die, those cards are exiled instead
Whether the card will end up going for as much as he hopes remains to be seen
they may have additional effects like drawing cards, inflicting Special Conditions (Asleep, Burned, Confused, Paralyzed, or Poisoned) or altering the opponent's deck and/or board state
Should any of the missing cards begin to see play and cause paper and Arena play to diverge, they will be added to Arena to maintain parity
