Invasion of Arcavios // Invocation of the Founders + Chandra, Hope's Beacon + Flicker + Vampire Hexmage + Invasion of Tolvada // The Broken Sky

Invasion of Arcavios // Invocation of the Founders

Chandra, Hope's Beacon

Flicker

Vampire Hexmage

Invasion of Tolvada // The Broken Sky

How it works

1. Activate Vampire Hexmage by sacrificing it, removing all counters from Invasion of Arcavios.
2. Invasion of Arcavios triggers, causing you to exile it and cast it as Invocation of the Founders.
3. Activate Chandra's first ability by putting a loyalty counter on it, adding 1.
4. Cast Flicker by paying 1, targeting Invocation of the Founders.
5. Chandra and Invocation of the Founders trigger, copying Flicker twice, with one copy targeting Chandra and the other targeting Invasion of Tolvada.
6. Resolve the first Flicker copy, blinking Chandra.
7. Resolve the second Flicker copy, blinking Invasion of Tolvada.
8. When Invasion of Tolvada enters the battlefield, it triggers, returning Vampire Hexmage to the battlefield from your graveyard.
9. Resolve the original Flicker, blinking Invocation of the Founders, causing it to enter the battlefield as Invasion of Arcavios.
10. When Invasion of Arcavios enters the battlefield, it triggers, returning Flicker to your hand from your graveyard.
11. Repeat.

This intricate loop spins up infinite spells and triggers by exploiting the unique ability of Sieges to transform when all defense counters are removed. Vampire Hexmage initiates this cycle by sacrificing itself to immediately strip the counters off Invasion of Arcavios, flipping it into Invocation of the Founders while grabbing Flicker from your graveyard or library. Once cast, Flicker is multiplied by both Chandra, Hope's Beacon and Invocation of the Founders, allowing you to reset Chandra, blink the transformed siege back into its front side, and continuously recur Vampire Hexmage and Invasion of Tolvada.
