Archon of Emeria and Eye of the Storm on the battlefield.
Steps
Whenever a player casts an instant or sorcery spell, Eye of the Storm triggers, exiling that spell.
Because Archon of Emeria 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.
Results
Exile all instant and sorcery spells players cast.
