Bilbo, Retired Burglar + Myojin of Cryptic Dreams + Xorn + Time Sieve

Bilbo, Retired Burglar

Myojin of Cryptic Dreams

Xorn

Time Sieve

How it works

1. Cast Xorn by paying 2.
2. Holding priority, activate Myojin by removing an indestructible counter from it, copying the Xorn spell three times.
3. Resolve all Xorn spells.
4. Deal combat damage to an opponent using Bilbo.
5. Bilbo's second ability triggers, creating five Treasure tokens due to the four Xorns.
6. Activate Time Sieve by tapping it and sacrificing the Treasures, causing you to take an extra turn after this one.
7. Repeat from step 4 each turn.

By casting Myojin of Cryptic Dreams from your hand and stripping its indestructible counter right as you cast Xorn, you pull off a magnificent duplication trick that clutters the board with multiple copies of Xorn. With this mechanical army in play, every time Bilbo, Retired Burglar connects in combat and triggers its treasure-producing damage ability, Xorn's replacement effect amplifies that single strike into a massive haul of five Treasure tokens. You can then feed this glittering horde directly into Time Sieve to take infinite extra turns, locking your opponents out of the game entirely.
