Stealth When a J/resonator is destroyed. (While this card is in your standby area, you may play it without paying its cost if its Stealth condition is met.)

Players cannot play activate abilities of rulers or sub-rulers.

If an effect would increase ATK and/or DEF of a J/resonator your opponent controls, it does not increase it instead.

Resonance Light Magic Stone ⇒ Remove the top three cards of your opponent's deck from the game face down.
