Death-Rattle Oni⁣ - March of the Machine: The Aftermath⁣ (Uncommon)⁣ [13]

Death-Rattle Oni has Flash, allowing you to surprise opponents by casting it in response to their attacks. Its cost reduction based on the number of creatures that died this turn makes it easier to play in decks focused on creature removal or sacrifice strategies. When it enters, it wipes out all other creatures that took damage, providing a significant board advantage and potentially clearing the way for your own attacks.
