Aminatou, the Fateshifter

Ichormoon Gauntlet

Doubling Season

Liliana, Dreadhorde General

How it works

1. Activate Aminatou's second loyalty ability by removing a loyalty counter from it, blinking Liliana.
2. Liliana enters the battlefield with twelve loyalty counters due to Doubling Season.
3. Activate any other planeswalker you control by putting zero loyalty counters on it, putting a loyalty counter on Aminatou and Liliana.
4. Activate Liliana by removing twelve loyalty counters from it, causing you to take an extra turn after this one.
5. Repeat each turn.
