Myojin of Cryptic Dreams + Adaptive Sporesinger

Myojin of Cryptic Dreams

Adaptive Sporesinger

How it works

1. Cast Adaptive Sporesinger by paying its mana cost.
2. Holding priority, activate Myojin by removing an indestructible counter from it, copying the Adaptive Sporesinger spell three times.
3. Resolve the first Adaptive Sporesinger spell.
4. When the Adaptive Sporesinger token enters the battlefield, it triggers, putting an indestructible counter on Myojin.
5. Repeat from step 2.

This loop turns Myojin of Cryptic Dreams into an infinite spell-copying engine by exploiting the fact that its activation requires removing an indestructible counter rather than tapping. When you cast Adaptive Sporesinger, Myojin copies that creature spell multiple times, and each entering token triggers its own entry ability to proliferate and successfully replenish the exact indestructible counter you just removed. Because Myojin doesn't need to tap, you can repeat this process endlessly to generate an army of tokens and infinite proliferation triggers.
