Aberrant Mind Sorcerer + Helm of the Host + Walk the Aeons

Aberrant Mind Sorcerer

Helm of the Host

Walk the Aeons

How it works

1. Cast Walk the Aeons by paying 4, 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 Walk the Aeons from your graveyard to your hand, or put Walk the Aeons from your graveyard on top of your library.
4. Move to your extra turn, drawing Walk the Aeons if it was put on top of your library.
5. Repeat.

This clever loop hinges on recurring extra turns by combining a creature's enter-the-battlefield trigger with a repeating token generator. When Helm of the Host equips to Aberrant Mind Sorcerer, it creates a fresh token copy at the start of combat every single turn, which neatly bypasses the usual legendary restrictions. Each time that token enters the battlefield, its Psionic Spells ability lets you roll a d20 to retrieve the Walk the Aeons you previously cast from your graveyard back to your hand or onto your library. Since Walk the Aeons grants you an immediate extra turn, you can simply draw the spell or replay it endlessly, chaining infinite turns together to lock down the game.
