Asheal, Angel of Sacrifice

As long as Asheal, Matyr of Sacrifice is in the
command zone, players can't sacrifice
permanents or pay life to activate abilities or cast spells.
Flying, persist, indestructible
If a player would sacrifice a permanent to cast a
spell or activate an ability, you may sacrifice
Asheal instead and counter it. If you do,
each player copies that spell or ability. You may
choose new targets for each.
