Partner with Sprig, Anne's Best Friend

Creatures you control have vigilance.

Whenever a source an opponent controls causes another legendary creature you control to leave the battlefield or take damage, exile Anne of Azure Heart, then return her to the battlefield transformed under her owner’s control. Then add {r}{r} at the beginning of your next main phase.

: Anne is a Human Soldier creature with power and toughness each equal to the number of loyalty counters on her with indestructible that's still a planeswalker.

If a source would deal damage to Anne, prevent all but 2 of that damage.

If Anne would die, transform her instead.

-X: Choose X for Anne to gain until your next turn from among flying, hexproof, first strike, vigilance, trample, and menace.
