Isochron Scepter + Swarm Intelligence + Dream's Grip + Lotus Field

Isochron Scepter

Swarm Intelligence

Dream's Grip

Lotus Field

How it works

1. Activate Lotus Field by tapping it, adding three mana of any color.
2. Activate Isochron Scepter by paying 2 and tapping it, casting a copy of Dream's Grip without paying its mana cost, targeting Isochron Scepter.
3. Swarm Intelligence triggers, creating a copy of Dream's Grip, targeting Lotus Field.
4. Resolve both Dream's Grips, untapping Isochron Scepter and Lotus Field.
5. Repeat.
