Illuminor Szeras + Myr Battlesphere + Grenzo, Dungeon Warden + Reito Sentinel + Clock of Omens

Illuminor Szeras

Myr Battlesphere

Grenzo, Dungeon Warden

Reito Sentinel

Clock of Omens

How it works

1. Activate Illuminor Szeras by tapping it and sacrificing Myr Battlesphere, adding seven .
2. Activate Reito Sentinel by paying 3, putting Myr Battlesphere on the bottom of your library.
3. Activate Grenzo by paying 2, putting Myr Battlesphere from the bottom of your library into your graveyard, then putting it onto the battlefield.
4. When Myr Battlesphere enters the battlefield, it triggers, creating four 1/1 Myr artifact creature tokens.
5. Activate Clock of Omens by tapping Myr Battlesphere and a Myr token, untapping Illuminor Szeras.
6. Repeat.

This intricate loop relies on looping Myr Battlesphere through your library and graveyard to generate infinite resources, fueled by Illuminor Szeras sacrificing the Battlesphere for seven black mana. To make this endless cycle possible, Reito Sentinel tucks the sacrificed Myr Battlesphere back onto the bottom of your library so that Grenzo, Dungeon Warden can pay two mana to cheat it directly back into play, replenishing its four Myr tokens upon entry. Meanwhile, Clock of Omens acts as the vital mechanical grease, letting you tap the newly arrived Myr Battlesphere alongside one of its tokens to untap Illuminor Szeras and keep the whole engine running.
