The Tenth Doctor + Mana Echoes + Cyclical Evolution + Saheeli, Sublime Artificer

The Tenth Doctor

Mana Echoes

Cyclical Evolution

Saheeli, Sublime Artificer

How it works

1. Activate The Tenth Doctor by paying 7, removing all time counters from Cyclical Evolution.
2. Cyclical Evolution triggers, causing you to cast it from exile without paying its mana cost.
3. Saheeli, Sublime Artificer triggers, creating a creature token.
4. When the creature token enters, Mana Echoes triggers, adding C for each creature you control that shares a creature type with the token.
5. Resolve Cyclical Evolution.
6. Repeat.

This dazzling loop turns the time-manipulating prowess of The Tenth Doctor into a runaway manufacturing plant, fueled by the explosive mana production of Mana Echoes. When you cast Cyclical Evolution from exile, Saheeli, Sublime Artificer steps in to forge a Servo token, which immediately swells your creature count and maximizes the colorless mana generated by Mana Echoes to fund The Tenth Doctor's hefty {7} time-travel activation. By rapidly stripping away Cyclical Evolution's time counters, you replay the spell over and over, letting Saheeli, Sublime Artificer's −2 ability also copy key permanents if needed while flooding the battlefield with an endless army of artifact creatures.
