Displacer Kitten + Intruder Alarm + Shackles

Displacer Kitten

Intruder Alarm

Shackles

How it works

1. Activate any number of creatures you control by tapping them, adding at least 2.
2. Cast Shackles 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 Shackles spell.
6. Activate Shackles by paying , returning it from the battlefield to your hand.
7. Repeat.

This clever loop relies on Intruder Alarm to turn every cast into a mass untap for your tapped creatures, feeding a continuous stream of mana. By repeatedly casting Shackles, you trigger Displacer Kitten's blink ability to reset the Kitten itself, which in turn forces Intruder Alarm to untap your entire board so you can tap them for mana all over again. Finally, the ability on Shackles lets you bounce the Aura right back to your hand for a single white mana so you can start the whole cycle anew.
