Forum:Bottomless vs caius

if my opponent summons Caius and i have a monster and a face down bottomless when he summons caius and i activate my bottomless does he still be able to use caius effect to destroy one card on the field if it is the monster is it destroyed? and if he choses my face down bottomless is he destroyed?? or nothing happens due to the fact that i chained bottomless to his summon?
