Ikit Claw, Arch-Warlock

When Ikit Claw enters, create a legendary artifact called Doomsphere with "{2}{t}: Put a charge counter on Doomsphere. {t}, Sacrifice Doomsphere: deal damage to all creatures opponents control equal to the number of charge counters on Doomsphere."

Whenever you cast an Artifact or Rat spell, create a treasure token.
