Bound in Heaven

Creatures can't attack you unless their controller pays {2} for each creature they control
that's attacking you.

"I saw an angel coming down from heaven, holding
in his hand the key to the bottomless pit and a great
chain. And he seized the dragon, that ancient serpent, who is the devil and Satan, and bound him for a thousand years and threw him into the pit, and shut it and sealed it over him." –Rev. 20:1-3
