Medomai the Ageless + Assimilation Aegis + Balan, Wandering Knight

Medomai the Ageless

Assimilation Aegis

Balan, Wandering Knight

How it works

1. Declare Balan as an attacker.
2. Holding priority, activate Balan by paying 1, attaching Assimilation Aegis to it.
3. Assimilation Aegis' second ability triggers, causing Balan to become a copy of Medomai the Ageless.
4. Deal combat damage with Balan.
5. Balan triggers, causing you to take an extra turn after this one.
6. Move to your next turn.
7. Activate Assimilation Aegis' equip ability by paying 2, attaching it to any other creature you control.
8. Assimilation Aegis' second ability triggers, causing the creature to become a copy of Medomai the Ageless.
9. Repeat.

This clever loop takes advantage of how Assimilation Aegis dynamically updates a creature's identity the moment it becomes attached. By leveraging Balan, Wandering Knight's ability to instantly snap the Equipment onto itself at instant speed—transforming Balan into a copy of Medomai the Ageless mid-combat—you bypass Medomai's restriction against attacking during extra turns since the card entering combat wasn't originally named Medomai. Once the damage is dealt and the extra turn is secured, you simply shift the Assimilation Aegis to another creature to reset the process for the next cycle, locking down infinite turns.
