Isochron Scepter + Reclaim + Time Warp

Isochron Scepter

Reclaim

Time Warp

How it works

1. Cast Time Warp by paying 3, taking an extra turn after this one.
2. Activate Isochron Scepter by paying 2, casting a copy of Reclaim without paying its mana cost.
3. Resolve the Reclaim, returning Time Warp from your graveyard to your top of your library.
4. Move to your next turn.
5. Repeat.
