Extravagant Replication + Ardent Elementalist + Notorious Throng

Extravagant Replication

Ardent Elementalist

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

This mesmerizing engine takes flight the moment you successfully connect with a Rogue, allowing you to cast Notorious Throng for its prowl cost and seize an extra turn. Once you're safely in that bonus turn, Extravagant Replication steps in during your upkeep to steadily manufacture a token copy of Ardent Elementalist. Because that Ardent Elementalist token's triggered ability recycles Notorious Throng straight back from your graveyard to your hand, you secure an unending loop of infinite turns and complete battlefield lock.
