307.1. A player who has priority may cast a sorcery card from their hand during a main phase of their turn when the stack is empty. Casting a sorcery as a spell uses the stack. (See rule 601, “Casting Spells.”)
307.2. When a sorcery spell resolves, the actions stated in its rules text are followed. Then it’s put into its owner’s graveyard.
307.3. Sorcery subtypes are always a single word and are listed after a long dash: “Sorcery — Arcane.” Each word after the dash is a separate subtype. The set of sorcery subtypes is the same as the set of instant subtypes; these subtypes are called spell types. Sorceries may have multiple subtypes. See rule 205.3k for the complete list of spell types.
307.4. Sorceries can’t enter the battlefield. If a sorcery would enter the battlefield, it remains in its previous zone instead.
307.5. If a spell, ability, or effect states that a player can do something only “any time they could cast a sorcery” or “only as a sorcery,” it means only that the player must have priority, it must be during the main phase of their turn, and the stack must be empty. The player doesn’t need to have a sorcery card they could cast. Effects that would preclude that player from casting a sorcery spell don’t affect the player’s capability to perform that action (unless the action is actually casting a sorcery spell).
307.5a Similarly, if an effect checks to see if a spell was cast “any time a sorcery couldn’t have been cast,” it’s checking only whether the spell’s controller cast it without having priority, during a phase other than their main phase, or while another object was on the stack.
