Brinelin, the Moon Kraken + Invasion of Arcavios // Invocation of the Founders + Nexus of Fate

Brinelin, the Moon Kraken

Invasion of Arcavios // Invocation of the Founders

Nexus of Fate

How it works

1. Cast Invasion of Arcavios by paying 3.
2. When Invasion of Arcavios enters the battlefield, it triggers, returning Nexus of Fate from your graveyard to your hand, or searching your library for Nexus of Fate and putting it into your hand, if needed.
3. Cast Nexus of Fate by paying 5.
4. Brinelin triggers, returning Invasion of Arcavios to your hand from the battlefield.
5. Resolve Nexus of Fate, causing you to take an extra turn after this one and shuffle it into your library.
6. Repeat each turn.

This elegant loop is anchored by Nexus of Fate, which provides both your infinite extra turns and a built-in safety net that shuffles it right back into your library whenever it would hit the graveyard. To keep the engine running, you cast Invasion of Arcavios to tutor for your crucial spell while its back side, Invocation of the Founders, sits ready to copy your future instant and sorcery casts if needed. Every time you cast that expensive extra-turn spell, Brinelin, the Moon Kraken triggers off its high mana value to bounce Invasion of Arcavios right back to your hand, allowing you to replay the Siege, reset your tutor, and take all the time in the world.
