Anaphiel, Breaker of Chains

Flying, provoke (Whenever this creature attacks,
you may have target creature defending player controls
untap and block it if able.)
Creatures blocking or blocked by Anaphiel are
removed from combat, then those creatures' controller losses control of them. (Spells and
effects with "control" cannot target or effect creatures
with no controller. Players can't attack, block or
activate abilities of creatures they don't control.)
