Displacer Kitten + Intruder Alarm + Crown of Flames

Displacer Kitten

Intruder Alarm

Crown of Flames

How it works

1. Activate any number of creatures you control by tapping them, adding at least .
2. Cast Crown of Flames by paying its mana cost, targeting any creature you control except Displacer Kitten.
3. Displacer Kitten triggers, blinking itself.
4. When Displacer Kitten enters the battlefield, Intruder Alarm triggers, untapping all creatures.
5. Resolve the Crown of Flames spell.
6. Activate Crown of Flames by paying , returning it from the battlefield to your hand.
7. Repeat.

This delightful loop turns the humble Crown of Flames into an engine for infinite mana and triggers, provided your creatures can tap to produce at least two red mana. Each time you recast the Aura, Displacer Kitten blinks itself to trigger Intruder Alarm, which in turn untaps all your mana-producing creatures so you can pay to return Crown of Flames to your hand and do it all over again.
