River Song + Conjurer's Bauble + Salvaging Station + Notorious Throng

River Song

Conjurer's Bauble

Salvaging Station

Notorious Throng

How it works

1. If Conjurer's Bauble is in your graveyard, activate Salvaging Station by tapping it, returning Conjurer's Bauble from your graveyard to the battlefield.
2. Deal combat damage to an opponent using a Rogue.
3. Cast Notorious Throng for its prowl cost by paying 5, causing you to take an extra turn after this one.
4. Activate Conjurer's Bauble 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.
