Knight's Final Curse

Enchant player
When Knight's Final Curse enters the battlefield, choose two target creatures enchanted player
controls. If you do, put five curse counters on
Knight's Final Curse. At the beginning of your upkeep, remove a curse counter from it if any of
the chosen creatures remain on the battlefield.
Then, if there are no curse counters on Knight's
Final Curse, sacrifice it and create a 9/9 white
and black Spirit creature token with flying.
