+1: Until end of turn, target Creature you control gets +1/+1 and gains first strike, vigilance, and lifelink.
-2: Put a +1/+1 counter on each Creature you control and a loyalty counter on every other planeswalker you control.
-7: For the rest of the game, if a source would deal damage to you or a planeswalker, prevent all but one of that damage.
