Impostor Syndrome + Time Sieve + Myr Battlesphere Combo

All permanents on the battlefield (Myr Battlesphere without summoning sickness on the battlefield).

An opponent cannot block Myr Battlesphere.

Deal combat damage to an opponent using Myr Battlesphere, triggering Impostor Syndrome, creating a token copy of Myr Battlesphere.

When the Myr Battlesphere token enters, it triggers, creating four 1/1 Myr artifact creature tokens.

Activate Time Sieve by tapping it, sacrificing the four Myr tokens and sacrificing the Myr Battlesphere token, causing you to take an extra turn after this one.

Repeat each turn.
