Deathtouch, Vigilance

At the beginning of your upkeep, put a Stun counter on X other nonland permanents, where X is Alanna's power.

Whenever a Stun counter becomes removed from a permanent an opponent controls, that permanents controller may pay {1}, if they choose not to, create a 2/2 white Knight creature token with Vigilance or put a +1/+1 counter on Alsanna.
