If a player ends their turn without casting spells, playing units, or triggering abilities, does priority pass to the opponent to give them an opportunity to cast a spell before the turn ends?
Ruling: No, ending your turn with no abilities activating does not create an opportunity for your opponent to play a spell. There needs to be something on the stack (like abilities, spells, or combat) for your opponent to respond to.
Nuances:
- Playing units or gear creates a chain, but no priority is given before they resolve
- Actions like playing a unit, drawing a card, or generating energy/power don't create response opportunities by themselves
- If a unit has a "When you play" ability, that ability initiates a new chain after the permanent resolves, which does pass priority
- Movement itself doesn't create a response opportunity, but on-move effects do create a stack
