Emma the Gentle Blade

First strike, Lifelink

Whenever a creature you control would die, you may pay {w}. If you do, prevent that damage and instead tap it and it gains Hexproof until your next turn. At the beginning of your end step, if you control another legendary creature, you may gain 2 life and untap Emma.

Whenever you gain life, you may put a +1/+1 counter on another creature you control. At the beginning of each end step, if you gained 5 or more life this turn, untap all creatures you control.
