River Song + Conjurer's Bauble + Saheeli, the Sun's Brilliance + Time Warp

River Song

Conjurer's Bauble

Saheeli, the Sun's Brilliance

Time Warp

How it works

1. Activate Saheeli by paying and tapping it, creating a token copy of Conjurer's Bauble.
2. Cast Time Warp by paying its mana cost, causing you to take an extra turn after this one.
3. Activate the Conjurer's Bauble token by tapping and sacrificing it, putting Time Warp onto the bottom of your library from your graveyard, and then causing you to draw Time Warp from the bottom of your library due to River Song.
4. Repeat each turn.
