Shrine of Boundless Blessings

Creatures you control can't attack.
If you don't control a Forest, sacrifice Shrine of Boundless Blessings.
At the beginning of your upkeep, create a
colorless land token with "{t}: Add {c}.".
It comes into play tapped.
Whenever you are dealt damage by a creature with power 5 or greater, that creatures' controller gains control of Shrine of Boundless Blessings.
