At the beginning of your upkeep, choose one that hasn't been chosen — • This enchantment deals 4 damage to any target and you gain 4 life. • Target opponent discards two cards. • Draw two cards. • You lose the game.

Counter target spell. At the beginning of your next upkeep, pay {3}{U}{U}. If you don't, you lose the game.

+1: Until your next turn, prevent all damage target permanent would deal. 0: Until end of turn, Gideon becomes a 4/4 Human Soldier creature with indestructible that's still a planeswalker.
