Luminous Broodmoth + Mikaeus, the Lunarch + Solemnity

Luminous Broodmoth

Mikaeus, the Lunarch

Solemnity

How it works

1. Cast Mikaeus with X=0.
2. Mikaeus dies due to having 0 toughness.
3. Luminous Broodmoth returns Mikaeus to the battlefield.
4. Repeat for step 2 for a mandatory loop that draws the game.

This loop turns Solemnity's strict prohibition on counters into a fatal catalyst for your own board. With Solemnity preventing any counters from being placed, Mikaeus, the Lunarch enters with zero toughness and instantly perishes upon hitting the battlefield. Luminous Broodmoth steps in to rescue the fallen cleric, returning it immediately because Mikaeus lacked flying when it died—giving it a flying counter that Solemnity instantly blocks. This creates an unstoppable, mandatory cycle of endless deaths and rebirths that will force a draw unless someone can break the lock.
