Fought dark world deck. He ss Ceruli on my field.. Ss Reign Beaux he chose destroy s/t lucky at that moment i have forbidden chalice. Protected my other two traps.. This card should be SR for Reign Beaux
I don't think Ceruli makes you discard, I think it makes your opponent discard even tho it's on his field. There is a card that does something like that when you give it to your opponent but I can't remember it now.
