Kykar, Zephyr Awakener + Vampire Charmseeker + Walk the Aeons

Kykar, Zephyr Awakener

Vampire Charmseeker

Walk the Aeons

How it works

1. Cast Walk the Aeons by paying its mana cost.
2. Kykar triggers, exiling Vampire Charmseeker.
3. Resolve Walk the Aeons, causing you to take an extra turn after this one.
4. At the beginning of your end step, Kykar triggers, returning Vampire Charmseeker from exile to the battlefield.
5. When Vampire Charmseeker enters, it triggers, returning Walk the Aeons from your graveyard to your hand.
6. Repeat each turn.

This elegant loop achieves infinite turns by recycling a single copy of Walk the Aeons straight from your graveyard back to your hand. The engine is anchored by Kykar, Zephyr Awakener, whose cast trigger safely exiles Vampire Charmseeker during your main phase and returns it to the battlefield just in time for the end step. When Vampire Charmseeker reappears, its enters-the-battlefield ability triggers to retrieve Walk the Aeons, readying the entire sequence to repeat on your next extra turn.
