Magosi, the Waterveil + The Ozolith + Nature's Revolt + Contagion Clasp

Magosi, the Waterveil

The Ozolith

Nature's Revolt

Contagion Clasp

How it works

1. During your precombat main phase, activate Contagion Clasp by paying 4 and tapping it, putting an eon counter on Magosi.
2. Activate Magosi's third ability by tapping it, removing an eon counter from it and returning it from the battlefield to your hand.
3. When Magosi leaves the battlefield, The Ozolith's first ability triggers, putting an eon counter on The Ozolith.
4. Resolve the Magosi ability, causing you to take an extra turn after this one.
5. Play Magosi.
6. At the beginning of your combat phase, The Ozolith triggers, putting an eon counter on Magosi.
7. Repeat each turn.

This intricate loop twists time itself by turning Magosi, the Waterveil into a self-sustaining extra-turn engine, all made possible by Nature's Revolt waking up your lands into creatures so The Ozolith can watch them leave the battlefield. When you bounce Magosi to your hand to trigger its extra turn, The Ozolith catches its eon counter, preserving it safely away from the land's typical self-exiling restriction. Then, after replaying the land, The Ozolith hands that eon counter right back to Magosi during your combat step, perfectly bypassing the need to ever skip a turn. Meanwhile, Contagion Clasp sits ready to manipulate counters if needed, keeping your temporal machinery running smoothly on loop.
