Intruder Alarm + Harmonized Trio // Brainstorm + Rite of the Dragoncaller

Intruder Alarm

Harmonized Trio // Brainstorm

Rite of the Dragoncaller

How it works

1. Activate a creature by tapping it, adding at least .
2. Activate Harmonized Trio by tapping it and two other creatures you control, causing it to become prepared.
3. Cast a copy of Brainstorm by paying .
4. Rite of the Dragoncaller triggers, creating a creature token.
5. When the creature token enters, Intruder Alarm triggers, untapping all creatures.
6. Resolve Brainstorm, causing you to draw three cards and put two cards from your hand onto the top of your library.
7. Repeat.

This clever loop relies on Harmonized Trio's ability to repeatedly cast copies of Brainstorm by leveraging its prepared mechanic, fueled by whatever creature is tapping to provide the initial mana. Every time a copy of Brainstorm is cast, Rite of the Dragoncaller rewards you by hatching a 5/5 red Dragon token with flying. That fresh creature arrival immediately triggers Intruder Alarm, bypassing everyone's normal untap steps to effortlessly ready all your creatures for another iteration.
