Teferi, Timebender + Luxior, Giada's Gift + Eldrazi Displacer + Doubling Season

Teferi, Timebender

Luxior, Giada's Gift

Eldrazi Displacer

Doubling Season

How it works

1. Activate Luxior's first equip ability by paying 1, attaching it to Teferi.
2. Activate Eldrazi Displacer by paying 2C, blinking Teferi, which enters the battlefield with ten loyalty counters due to Doubling Season.
3. Activate Teferi's third loyalty ability by removing nine loyalty counters from it, causing you to take an extra turn after this one.
4. Repeat each turn.

By wrapping Luxior, Giada's Gift around Teferi, Timebender, we transform our planeswalker into a creature while preserving its ability to use loyalty powers. Eldrazi Displacer then steps in to repeatedly blink Teferi, and because Doubling Season is sitting passively on the battlefield, every time Teferi re-enters, it doubles the incoming loyalty counters to a massive total of ten. This lets you immediately fire off Teferi's -9 ultimate for an extra turn, resetting the loop so you can indefinitely lock down the game and take all the time you need.
