Progenitor Mimic + Salvager of Secrets + Notorious Throng

Progenitor Mimic

Salvager of Secrets

Notorious Throng

How it works

1. Deal combat damage to an opponent using a Rogue.
2. Cast Notorious Throng for its prowl cost by paying 5, causing you to take an extra turn after this one.
3. At the beginning of your next upkeep, Progenitor Mimic triggers, creating a token copy of Salvager of Secrets.
4. When the Salvager of Secrets token enters the battlefield, it triggers, returning Notorious Throng from your graveyard to your hand.
5. Repeat.

This clever loop starts by dealing combat damage with a Rogue to set up Notorious Throng for its prowl cost, granting you an extra turn while flooding the board with Faerie Rogue tokens. When your next turn begins, Progenitor Mimic's upkeep trigger creates a token copy of Salvager of Secrets. That token's enter-the-battlefield ability then reaches into your graveyard to pull Notorious Throng right back to your hand, ready to be cast again on your extra turn to repeat the cycle indefinitely.
