"Once per turn: You can detach 1 Xyz Material from this card, then target 1 monster on the field with ATK less than or equal to the combined ATK of all 'Ghostrick' monsters on the field; destroy that target, and if you do, that monster's Monster Zone cannot be used as long as a 'Ghostrick' monster is face-up on your field." monster effect is an Ignition Effect. (Detaching 1 Xyz Material from this card is a cost to activate this effect.)

The monster effect of "Ghostrick Succubus" that is activated by detaching an Xyz Material is considered to resolve when the targeted monster is destroyed. (The effect "that monster's Monster Zone cannot be used as long as a 'Ghostrick' monster is face-up on your field" is also applied immediately.)

The monster effect of "Ghostrick Succubus" that is activated by detaching an Xyz Material targets 1 face-up monster in either player's Monster Zone. (You can only target a monster with ATK less than or equal to the combined ATK of all face-up "Ghostrick" monsters in either player's Monster Zone.)

"While you control another 'Ghostrick' monster, your opponent cannot target this card for attacks." monster effect is a Continuous Effect.
