Medomai the Ageless + Idris, Soul of the TARDIS + Sword of Truth and Justice + Transmogrifying Licid

Medomai the Ageless

Idris, Soul of the TARDIS

Sword of Truth and Justice

Transmogrifying Licid

How it works

1. Deal combat damage to an opponent using Medomai the Ageless.
2. Medomai the Ageless triggers, causing you to take an extra turn after this one.
3. Cast Idris by paying 1.
4. When Idris enters the battlefield, it triggers, exiling Medomai the Ageless until Idris leaves the battlefield.
5. Activate Sword of Truth and Justice's equip ability by paying 2, attaching it to Idris.
6. Move to your extra turn.
7. At the beginning of your upkeep, Idris's vanishing ability triggers, removing a time counter from it.
8. Deal combat damage to an opponent using Idris.
9. Idris and Sword of Truth and Justice trigger.
10. Resolve the Idris trigger, causing you to take an extra turn after this one.
11. Resolve the Sword of Truth and Justice trigger, putting a +1/+1 counter on a creature you control, then putting a time counter on Idris.
12. Repeat from step 6.

This clever loop circumvents Medomai the Ageless's restriction against attacking during extra turns by letting Idris, Soul of the TARDIS step into the spotlight. When Idris enters the battlefield, its imprint ability tucks away Medomai the Ageless, allowing Idris to completely adopt Medomai's famous extra-turn combat trigger. Equipped with Sword of Truth and Justice, Idris not only punches through defenses but also proliferates upon dealing combat damage, feeding the Sword's own counter addition right back into Idris's vanishing time counters to keep it alive indefinitely. Meanwhile, Transmogrifying Licid waits quietly in the wings as part of the setup, letting you assemble this mechanical symphony and chain endless extra turns.
