ruling acording to wikia
so if this scenario happens
turn player,standby phase
opponents activate ''skill drain''
*no response from turn player*
opponents chain ''vanity's emptiness''
turn player chains ''mystical space typhon'' targeting ''skill drain''
MST destroys skill drain, skill drain doesnt resolve now here is the question:
would vanity's emptiness be destroyed by its own effect? or is it a condition and as soon as skill drain touches the graveyard vanity's is destroyed?
i guess since vanity's starts a chain and one chain is resolving already i think it wont be destroying ,correct me if im wrong, thanks ;D
