Ezra, Beacon of Hope

Lifelink, Vigilance
Whenever you gain life, put a +1/+1 counter on
each other creature you control.
At the beginning of your end step, if you have at
least 30 life more than your starting life total and
you control five or more creatures, exile Ezra,
then return him to the battlefield transformed
under his owner's control.
"Even in the face of despair, we stand resolute."
- Ezra
