Pathetic Demise (Full Art) (CST-084 SR) [Clash of the Star Trees]

Play this card only if you control a J/ruler named "Sieben, Malefic $t@r". You pay 2 less to play this card for each Seven Kings ruler you own revealed outside the game. This card cannot be discarded by the effect of or as a cost of spells or abilities you control. Your opponent banishes seven resonators. If they don't, your opponent banishes a non-magic stone, non-J/resonator entity for each resonator not banished this way. If they don't, they discard a card for each entity not banished this way. If they don't, they lose 2000 life for each card not discarded this way.
