Arcane Laboratory + Eye of the Storm
Eye of the Storm
All permanents on the battlefield.
- Whenever a player casts an instant or sorcery spell, Eye of the Storm triggers, exiling that spell
- Because Arcane Laboratory prevents players from casting more than one spell each turn, players cannot cast the spell permitted by Eye of the Storm, or any other spell that turn
Players can only cast one spell per turn. Exile all instant and sorcery spells players cast.
