Teferi, Master of Time + Ichormoon Gauntlet + Oath of Teferi

Teferi, Master of Time

Ichormoon Gauntlet

Oath of Teferi

How it works

1. Activate Teferi by putting zero loyalty counters on it, putting a loyalty counter on itself.
2. Repeat step 1 twice for each other planeswalker you control.
3. Activate Teferi's third loyalty ability by removing ten loyalty counters from it, causing you to take two extra turns after this one.
4. Move to your first extra turn.
5. Repeat steps 1 and 2.
6. Move to your second extra turn.
7. Repeat.

By leveraging Oath of Teferi to double the activations of your planeswalkers and Ichormoon Gauntlet to grant a zero-cost proliferate ability, you can rapidly accumulate loyalty on Teferi, Master of Time. Teferi's static ability is crucial here, allowing you to trigger these loyalty abilities at instant speed on any player's turn, while Ichormoon Gauntlet's passive trigger even rewards your noncreature spells by adding extra counters. Once you hit the threshold, you cash in Teferi's ultimate to secure infinite turns, locking your opponents out of the game entirely.
