Magosi, the Waterveil + Nesting Grounds + Contagion Clasp

Magosi, the Waterveil

Nesting Grounds

Contagion Clasp

How it works

1. Activate Contagion Clasp by paying 4 and tapping it, putting an eon counter on Magosi.
2. Activate Nesting Grounds's last ability by paying 1 and tapping it, moving an eon counter from Magosi to Nesting Grounds.
3. Activate Magosi's last ability by tapping it, removing an eon counter from it and returning it to your hand, taking an extra turn after this one.
4. Play Magosi from your hand.
5. Move to your next turn.
6. Activate Contagion Clasp by paying 4 and tapping it, putting an eon counter on Nesting Grounds.
7. Activate Nesting Grounds's last ability by paying 1 and tapping it, moving an eon counter from Nesting Grounds to Magosi.
8. Repeat from step 3.

This brilliant loop turns Magosi, the Waterveil into a perpetual motion machine by completely bypassing its native drawback of skipping a turn. Normally, cashing in the land's eon counter sends it back to your hand without netting you a permanent engine, but Nesting Grounds steps in to solve that puzzle by safely warehousing the counter elsewhere. Meanwhile, Contagion Clasp provides the proliferation tool needed to multiply your resources and grease the wheels of the entire operation. By bouncing Magosi, replaying it, and shuffling the eon counter back and forth with Nesting Grounds, you effortlessly chain endless extra turns to lock down the game.
