Invasion of Arcavios // Invocation of the Founders

Hullbreaker Horror

Walk the Aeons

How it works

1. Cast Invasion of Arcavios by paying 3.
2. Hullbreaker Horror triggers, returning up to one nonland permanent to its owner's hand.
3. When Invasion of Arcavios enters the battlefield, it triggers, returning Walk the Aeons from your graveyard to your hand, or searching your library for Walk the Aeons and putting it into your hand, if needed.
4. Cast Walk the Aeons by paying 4.
5. Hullbreaker Horror triggers, returning Invasion of Arcavios to your hand from the battlefield.
6. Resolve Walk the Aeons, causing you to take an extra turn after this one.
7. Repeat each turn.

This brilliant loop gives you infinite turns by continuously resetting and re-casting Invasion of Arcavios, whose ETB trigger allows you to tutor Walk the Aeons straight from your graveyard or library. Once Walk the Aeons is cast to take your extra turn, the uncounterable Hullbreaker Horror steps in with its passive cast trigger, bouncing Invasion of Arcavios back to your hand so you can replay it and repeat the entire cycle.
