Extravagant Replication + Mnemonic Wall + Notorious Throng

Extravagant Replication

Mnemonic Wall

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 Mnemonic Wall.
5. When the Mnemonic Wall token enters the battlefield, it triggers, returning Notorious Throng from your graveyard to your hand.
6. Repeat.

This cunning loop lets you chain together infinite turns by repeatedly casting Notorious Throng, fueled by the extra turn it grants and its prowl cost. Extravagant Replication plays a pivotal role here by quietly setting up an engine at the beginning of each upkeep, automatically generating a fresh copy of Mnemonic Wall without needing further mana or card investment. Every time that Mnemonic Wall token enters the battlefield, its triggered ability immediately recycles Notorious Throng right back to your hand, ready to be cast again to sustain your endless sequence of turns.
