Magosi, the Waterveil + Forensic Researcher + Adric, Mathematical Genius

Magosi, the Waterveil

Forensic Researcher

Adric, Mathematical Genius

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 Forensic Researcher 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 Adric 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.

This loop achieves a brilliant mastery over time itself by exploiting Magosi, the Waterveil to bank extra turns while canceling out its own drawback. Normally, taking that skipped turn would set you back, but Forensic Researcher steps in to constantly ready Magosi so you can bounce it back to your hand with its counter already removed. The real magic happens when Adric, Mathematical Genius steps up to copy that extra-turn activation on the stack, effectively doubling your reward and letting you chain into infinite turns.
