Flash
When Godfrey enters the battlefield, put up to
one spell or permanent on top of its owner's
library.
Godfrey has reach as long as he is equipped.
Whenever Godfrey blocks a flying
creature, gain control of that creature until your opponent's next turn.
Equip abilities you control cost {1} less to activate,
and can be activated any time you could cast a
instant. (Adventurers are creatures)
