Synod Artificer + Thousand-Year Elixir + Empowered Autogenerator

Synod Artificer

Thousand-Year Elixir

Empowered Autogenerator

How it works

1. Activate Empowered Autogenerator's first ability by tapping it, putting a charge counter on it and adding at least three mana of any color.
2. Activate Synod Artificer's second ability by paying 2 and tapping it, untapping Thousand-Year Elixir and Empowered Autogenerator.
3. Activate Thousand-Year Elixir by paying 1 and tapping it, untapping Synod Artificer.
4. Repeat.

This delightful little engine revolves around Empowered Autogenerator, which grows its own mana production exponentially every time you cycle through the loop. To make this happen, Synod Artificer pulls double duty by using its tap ability to ready both the Autogenerator and Thousand-Year Elixir, while Thousand-Year Elixir's own activated ability repays the favor by immediately untapping Synod Artificer. Crucially, Thousand-Year Elixir's static ability is what ties the whole room together, granting haste to Synod Artificer so it can tap and untap right away without waiting around.
