Ephemerate + Walk the Aeons + Zealous Lorecaster

Ephemerate

Walk the Aeons

Zealous Lorecaster

How it works

1. Cast Walk the Aeons by paying its mana cost, causing you to take an extra turn after this one.
2. Cast Ephemerate by paying , blinking Zealous Lorecaster and exiling Ephemerate.
3. When Zealous Lorecaster enters, it triggers, returning Walk the Aeons from your graveyard to your hand.
4. Move to your next turn. At the beginning of your upkeep, Ephemerate's rebound ability triggers, causing you to cast it from exile without paying its mana cost.
5. Resolve Ephemerate, blinking Zealous Lorecaster.
6. When Zealous Lorecaster enters, it triggers, returning Ephemerate from your graveyard to your hand.
7. Repeat.

This elegant loop achieves infinite turns by recycling your extra-turn spell and your blink spell every single rotation. When you cast Walk the Aeons to secure another turn, Ephemerate sets up a perpetual recursion engine through its rebound ability and successive castings. Zealous Lorecaster acts as the crucial bridge for both spells, triggering its entry ability to pluck the necessary instant or sorcery straight from your graveyard back to your hand every time it blinks.
