Magosi, the Waterveil + Voyaging Satyr + Lithoform Engine

Magosi, the Waterveil

Voyaging Satyr

Lithoform Engine

How it works

1. Activate Magosi's second activated ability by paying and tapping it, putting an eon counter on Magosi and skipping your next turn.
2. Activate Voyaging Satyr by tapping it, untapping Magosi.
3. Activate Magosi's third activated ability by tapping it, removing an eon counter from it, and returning it to your hand.
4. Holding priority, activate Lithoform Engine by paying 2 and tapping it, copying Magosi's ability.
5. Resolve both instances of Magosi's ability, causing you to take two extra turns after this one.
6. Play Magosi.
7. Move to your second extra turn. The first extra turn will be skipped due to the ability activated in step 1.
8. Repeat.

By leveraging Magosi, the Waterveil's ability to bank extra turns at the cost of skipping a future one, we set up an engine to permanently hijack the turn order. Voyaging Satyr plays a crucial supporting role by untapping Magosi to help build up or reset the board state, while Lithoform Engine steps in to copy Magosi's third ability, effectively doubling the payout of extra turns gained when you bounce it back to your hand. Because you can replay Magosi each cycle, the penalty of skipping your next turn is entirely circumvented, resulting in an unbroken loop of infinite turns.
