Enchantment Creature — Spirit
Each player can't cast more than one spell each turn.

Eidolon of Rhetoric will look at the entire turn to see if a player has cast a spell yet that turn, even if Eidolon of Rhetoric wasn't on the battlefield when that spell was cast. Specifically, you can't cast Eidolon of Rhetoric and then cast another spell that turn.
