Aberrant Mind Sorcerer + Helm of the Host + Time Walk

Aberrant Mind Sorcerer

Helm of the Host

Time Walk

How it works

1. Cast Time Walk by paying 1, causing you to take an extra turn after this one.
2. At the beginning of your combat phase, Helm of the Host triggers, creating a token copy of Aberrant Mind Sorcerer with haste.
3. When the Aberrant Mind Sorcerer token enters the battlefield, it triggers, causing you to roll a d20 and either return Time Walk from your graveyard to your hand, or put Time Walk from your graveyard on top of your library.
4. Move to your extra turn, drawing Time Walk if it was put on top of your library.
5. Repeat.
