Six + Conjurer's Bauble + River Song + Gran-Gran

Six

Conjurer's Bauble

River Song

Gran-Gran

How it works

1. Activate Conjurer's Bauble by tapping and sacrificing it, putting a land from your graveyard onto the bottom of your library and causing you to draw the land.
2. Cast Conjurer's Bauble from your graveyard for its retrace cost by paying 0 and discarding a land.
3. Repeat.

This clever loop harnesses River Song's strange replacement effect, which turns your library upside down so you draw from the bottom instead of the top. By sacrificing Conjurer's Bauble, you tuck a card from your graveyard onto the bottom of your library and immediately draw it right back. Meanwhile, Six grants every nonland permanent in your graveyard retrace, allowing you to recast that very same Conjurer's Bauble by simply discarding a land. Gran-Gran sits on the sidelines helping to cycle cards in your hand as needed, ultimately fueling an endless cycle that generates infinite storm count, infinite self-discard triggers, and infinite draw triggers.
