2. Cast Snap by paying 1, targeting Skullwinder.

5. Activate Simic Growth Chamber and Lotus Field by tapping them, adding and three mana of any color.
6. Resolve Snap, returning Skullwinder from the battlefield to your hand and untapping Simic Growth Chamber and Lotus Field.
7. Cast Ivy by paying .
8. Cast Skullwinder by paying 2.
9. When Skullwinder enters the battlefield, it triggers, returning Snap from your graveyard to your hand, and causing an opponent to return any card from their graveyard to their hand.
10. Repeat.

This intricate loop spins up infinite mana and endless enters-the-battlefield triggers by leveraging the clever synergy of its pieces. You start by casting Snap to bounce Skullwinder, while Ivy, Gleeful Spellthief naturally triggers to copy the spell and bounce herself instead, keeping your engine intact. Each iteration relies on tapping both Simic Growth Chamber and Lotus Field for massive mana production before untapping them with your spells, leaving you with a net positive every single cycle. Finally, Skullwinder's entry ability recycles Snap right back to your hand so the entire process can begin anew.
