Prismari, the Inspiration + Fork

Prismari, the Inspiration

Fork

How it works

1. Cast any other instant or sorcery by paying its mana cost.
2. Holding priority, cast Fork by paying its mana cost, targeting the instant or sorcery cast in step 1.
3. Fork's storm ability triggers, creating at least one copy of Fork targeting the original Fork.
4. Resolve a copy of Fork, copying Fork targeting the original Fork.
5. Repeat step 4.
