Annalise, Blood Alchemist

At the end of each turn, if you gained 5 or more
life, draw a card. Whenever a creature enters
the battlefield, you get a blood counter.
Remove a Blood Counter: gain 1 life.
Pay X life: X target attacking creatures gain
lifelink until end of turn. If an opponent
gained life this way, gain half as much life
rounded up if you weren't attacked this turn.
