Time Sieve + Myr Battlesphere + Teleportation Circle + Doubling Season

Time Sieve

Myr Battlesphere

Teleportation Circle

Doubling Season

How it works

1. At the beginning of your end step, Teleportation Circle triggers, blinking Myr Battlesphere.
2. When Myr Battlesphere enters the battlefield, its first ability triggers, creating eight 1/1 Myr artifact creature tokens due to Doubling Season.
3. Activate Time Sieve by tapping it and sacrificing five Myrs, causing you to take an extra turn after this one.
4. Repeat each turn.

This loop locks down the game by chaining infinite turns, powered by a wonderfully synergistic cycle of creation and sacrifice. **Teleportation Circle** kicks things off at your end step by repeatedly blinking **Myr Battlesphere**, whose entrance triggers are amplified by **Doubling Season** to flood your board with eight Myr artifact tokens at a time. You then use those freshly minted tokens to fuel **Time Sieve**, sacrificing just five of them to take an extra turn. Because **Teleportation Circle** refreshes the Battlesphere every single turn, you get a fresh batch of tokens to sacrifice to **Time Sieve** on the next rotation, establishing an unyielding engine for infinite turns.
