Illuminor Szeras + Myr Battlesphere + Grenzo, Dungeon Warden + Soldevi Digger + Clock of Omens

Illuminor Szeras

Myr Battlesphere

Grenzo, Dungeon Warden

Soldevi Digger

Clock of Omens

How it works

1. Activate Illuminor Szeras by tapping it and sacrificing Myr Battlesphere, adding seven .
2. Activate Soldevi Digger by paying 2, 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 engine turns the high mana value of Myr Battlesphere into an endless loop by using Illuminor Szeras to sacrifice the colossal construct for a massive infusion of black mana. To keep the cycle going, Soldevi Digger tucks the Battlesphere back onto the bottom of your library, allowing Grenzo, Dungeon Warden to cheat it right back onto the battlefield to flood the board with new Myr tokens. Meanwhile, Clock of Omens acts as the mechanical heart that untaps Illuminor Szeras by tapping away your freshly minted artifacts, ensuring the whole operation can repeat indefinitely for infinite mana and tokens.
