Saheeli Rai + Liquimetal Torque + Mirror Box

Saheeli Rai

Liquimetal Torque

Mirror Box

How it works

1. Activate Liquimetal Torque's second ability by tapping it, causing Saheeli Rai to become an artifact until end of turn.
2. Activate Saheeli Rai's second loyalty ability by removing two loyalty counters from it, creating a token copy of itself that is an artifact in addition to its other types.
3. Repeat step 2.

This delightful loop turns the planeswalker Saheeli Rai into an endlessly copying machine by bypassing the legend rule entirely thanks to Mirror Box. Because Liquimetal Torque can temporarily turn Saheeli Rai into an artifact, her own -2 ability can target her and create an artifact copy of herself with haste. Mirror Box ensures you don't have to sacrifice any of your copies to the legend rule, allowing you to repeat the process to generate an arbitrary number of Saheeli Rai tokens.
