Aminatou, the Fateshifter + Spark Double + Oath of Teferi

Aminatou, the Fateshifter

Spark Double

Oath of Teferi

How it works

1. Activate Aminatou's second loyalty ability by removing a loyalty counter from them, blinking a permanent you own.
2. Activate Aminatou's second loyalty ability by removing a loyalty counter from them, blinking Spark Double and choosing to have it enter as a non-legendary copy of Aminatou.
3. Activate Spark Double's second loyalty ability by removing a loyalty counter from it, blinking a permanent you own.
4. Activate Spark Double's second loyalty ability by removing a loyalty counter from it, blinking Aminatou.
5. Repeat.

This wondrous loop relies on the clever synergy between Aminatou, the Fateshifter and Spark Double, where the clone enters safely devoid of the legendary supertype thanks to its own clever static ability. Because Oath of Teferi graces the battlefield with its passive blessing, both planeswalkers are granted the miraculous ability to activate their loyalty abilities twice each turn instead of just once. This allows Aminatou, the Fateshifter and the non-legendary Spark Double to endlessly blink one another back and forth, resetting their loyalty counters each time while continuously churning out infinite enter-the-battlefield triggers and untapped lands.
