Dismal Seraph

Flying
Whenever you activate an ability of a Pact, if
exactly one mana was spent to activate it, create
two 1/1 white and black Cleric creature tokens.
{3}: Inscribe. Activate only if you control three or
more Clerics. (Create a Pact token. It's an artifact
with "{4}, Sacrifice this artifact: Draw a card. This
ability costs {1} less to activate for each other creature
or Pact you've sacrificed this turn.")
