Atsushi, the Blazing Sky + Splinter Twin + Clock of Omens + Biotransference

Atsushi, the Blazing Sky

Splinter Twin

Clock of Omens

Biotransference

How it works

1. Activate Atsushi by tapping it, creating a token copy of it with haste.
2. Put the Atsushi token into your graveyard due to the legend rule.
3. When the Atsushi token dies, it triggers, creating three Treasure tokens.
4. Activate Clock of Omens by tapping two Treasures, untapping Atsushi.
5. Repeat

This loop transforms the legendary dragon Atsushi, the Blazing Sky into an infinite resource engine by turning it into an artifact through Biotransference. Once Biotransference makes Atsushi an artifact, Splinter Twin can enchant it and grant it the ability to tap out copies of itself, bypassing the legend rule through sacrifice. Each iteration of this token copy dying triggers Atsushi's ability to create three Treasure tokens. By feeding those newly minted Treasures along with another untapped artifact into Clock of Omens, you can continually untap Atsushi to repeat the process, generating infinite colored mana, infinite artifacts, and ultimately exiling your entire library with the ability to play those cards.
