Monk Gyatso + Spirit en-Kor + Advanced Reconstruction

Monk Gyatso

Spirit en-Kor

Advanced Reconstruction

How it works

1. Activate Spirit en-Kor by paying 0, targeting itself.
2. Monk Gyatso triggers, airbending Spirit en-Kor.
3. The Spirit en-Kor ability fizzles due to no longer having a legal target.
4. Cast Spirit en-Kor from exile by paying 0 due to Advanced Reconstruction.
5. Repeat.

This loop is a masterclass in turning a zero-mana activated ability into a self-sustaining engine. Spirit en-Kor can endlessly target itself for zero mana, and each of those targeting triggers immediately snaps Monk Gyatso into action to exile and airbend the Spirit. Meanwhile, the presence of Advanced Reconstruction acts as the ultimate catalyst: not only does its Level 3 cost-reduction make recasting the exiled Spirit for zero mana completely free, but any incidental card movement or graveyard interaction can also trigger its Level 2 ability to burn your opponents out of the game.
