Aran'gar (Balthamel Restored)

Aran'gar cannot be blocked
Whenever Aran'gar deals combat damage to a
player, exile target creature that player controls
and place a hit counter on that card. That player
loses the game if they own three or more exiled creatures with hit counters on them.
"She could destroy the lot of them, and even
dying they would never suspect who was killing
them."
