Inventory Management

After a spell with split second resolves (or otherwise leaves the stack), players may again cast spells and activate abilities before the next object on the stack resolves.

You can’t try to attach an Aura or Equipment to a creature if that Aura or Equipment can’t legally be attached to it.

Players still get priority while a spell with split second is on the stack; their options are just limited to mana abilities and certain special actions.
