Haakon, Stromgald Scourge + Maskwood Nexus + Ugin's Conjurant

Haakon, Stromgald Scourge

Maskwood Nexus

Ugin's Conjurant

How it works

1. Cast Ugin's Conjurant by paying 0.
2. Ugin's Conjurant dies as a state based action due to having zero toughness.
3. Repeat.

This loop relies on casting Ugin's Conjurant for zero mana so that state-based actions immediately send it to the graveyard. Maskwood Nexus makes every creature you own—including Ugin's Conjurant in the graveyard—every creature type, turning it into a Knight. That classification is all Haakon, Stromgald Scourge needs to let you recast Ugin's Conjurant straight from the graveyard over and over again, generating an endless stream of entries, exits, and deaths.
