What must be in place

You control a Rogue that does not have summoning sickness and that cannot be blocked by an opponent.

How to execute it

1. At the beginning of your upkeep, Mechanized Production triggers, creating a token copy of Conjurer's Bauble.
2. Deal combat damage to an opponent using a Rogue.
3. Cast Notorious Throng for its prowl cost by paying {5}{U}, causing you to take an extra turn after this one.
4. Activate the Conjurer's Bauble token by tapping and sacrificing it, putting Notorious Throng onto the bottom of your library from your graveyard, and then causing you to draw Notorious Throng from the bottom of your library due to River Song.
5. Repeat each turn.
