Extravagant Replication + Salvager of Secrets + Notorious Throng

Extravagant Replication

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. Move to your next turn.
4. At the beginning of your upkeep, Extravagant Replication triggers, creating a token copy of Salvager of Secrets.
5. When the Salvager of Secrets token enters the battlefield, it triggers, returning Notorious Throng from your graveyard to your hand.
6. Repeat.

This clever loop starts by casting Notorious Throng for its prowl cost, successfully taking an extra turn while sending the spell straight to your graveyard. Once your next turn rolls around, Extravagant Replication dutifully kicks off your upkeep by generating a fresh token copy of Salvager of Secrets. That newly manifested Salvager of Secrets token immediately triggers upon entering the battlefield, letting you fish Notorious Throng right back out of your graveyard and back into your hand. By repeating this process every single turn, you secure an endless succession of extra turns and lock the game down completely.
