## 9. Set and reveal traps

Pay a trap's Power cost on your turn to set it face down. It arms when that turn ends. You may hold at most three set traps. Setting a trap does not cast its spell effects.

During the printed window on the opponent's turn, reveal one eligible trap for free or pass to keep it hidden. Attack windows occur before combat damage; creature-play windows occur after the creature and its Boot-up resolve. The trap's printed subject determines its target. Finish any choices caused by the trap before the interrupted action continues.

You may discard a set trap to Junk on your turn to clear a slot, without a Power refund. Trap responses are specific windows; players do not otherwise respond to each effect with a general spell stack.
