Sage of Hours + Extruder + Myr Battlesphere + Emry, Lurker of the Loch

Sage of Hours

Extruder

Myr Battlesphere

Emry, Lurker of the Loch

How it works

1. Activate Emry by tapping it, targeting Myr Battlesphere.
2. Cast Myr Battlesphere from your graveyard by paying 7.
3. When Myr Battlesphere enters, it triggers, creating four 1/1 Myr artifact creature tokens.
4. Activate Extruder five times by sacrificing Myr Battlesphere and the four Myr tokens, putting five +1/+1 counters on Sage of Hours.
5. Activate Sage of Hours by removing all +1/+1 counters from it, causing you to take at least one extra turn after this one.
6. Repeat each turn.

This intricate machinery uses Emry, Lurker of the Loch to continuously pull Myr Battlesphere out of your graveyard, flooding the board with fodder tokens upon entry. Extruder readily turns that mechanical swarm—and the Battlesphere itself—into fuel, converting them into the five +1/+1 counters needed to power up Sage of Hours's extraordinary time-bending ability. Once Sage of Hours strips away those counters to grant you an extra turn, the loop simply resets on your next rotation, locking the game down in a glorious, unstoppable succession of infinite turns.
