Dream Halls + Conspiracy Theorist + Petals of Insight + Aethertide Whale

Dream Halls

Conspiracy Theorist

Petals of Insight

Aethertide Whale

How it works

1. Cast Petals of Insight by discarding Aethertide Whale.
2. Conspiracy Theorist triggers, exiling Aethertide Whale and allowing you to cast it from exile this turn.
3. Resolve Petals of Insight, putting the top three cards of your library on the bottom of your library, and returning Petals of Insight to your hand.
4. Cast Aethertide Whale from exile by discarding Petals of Insight.
5. Conspiracy Theorist triggers, exiling Petals of Insight and allowing you to cast it from exile this turn.
6. Aethertide Whale enters the battlefield, causing you to get six E.
7. Activate Aethertide Whale by paying EEEE, returning it to your hand from the battlefield.
8. Cast Petals of Insight from exile by discarding Aethertide Whale.
9. Repeat from step 2.

This fascinating loop transforms a pair of alternate-cost enablers into a perpetual motion machine by using Dream Halls to bypass mana costs through discarding. Conspiracy Theorist is the crucial bridge that keeps the chain alive, intercepting each discard to exile the discarded card and immediately grant permission to cast it from exile. Meanwhile, Petals of Insight constantly recycles itself back to your hand while manipulating your library, and Aethertide Whale provides the energy generation and bounce capability needed to reset the cycle. Together, these pieces feed each other indefinitely, letting you amass infinite energy and storm count without ever needing to tap a single land.
