Dihada, Binder of Wills + Underworld Breach + Mayhem Devil

Dihada, Binder of Wills

Underworld Breach

Mayhem Devil

How it works

1. Activate Dihada's second loyalty ability by removing three loyalty counters from it, causing you to reveal the top four cards of your library, put them into your graveyard, and create four Treasure tokens.
2. Activate the Treasures by tapping and sacrificing them, adding 1.
3. Mayhem Devil triggers four times, dealing enough damage to Dihada to cause it to be put into your graveyard, and dealing the remainder of the damage to any target(s).
4. Cast Dihada from your graveyard for its escape cost by paying 1 and exiling three cards from your graveyard.
5. Repeat.
