Tribute to Grakelkas

Destroy target creature with mana value 3
or less. Inscribe. (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.")

"My dark Lord, with this sacrifice, may your
transcendence be forever known!"
