Forum:Giant Soldier of Stone + Wicked Breaking FLamberge - Baou VS. Masked Dragon

When me and my friend were playing, this scenario happened.

Giant Soldier of Stone on my side, in attack, with Wicked Breaking FLamberge - Baou, equipped to it. And he had Masked Dragon.

It was understood that GIant Soldier of Stone was going to defeat Masked Dragon, but what rose a conflict, was him saying he got to take the card form his deck and summon it. I was against it, because Wicked-Breaking FLamberge - Baou negates the effect of a monster upon destroying in battle, which it did.

I'm just wondering, was it played right, or no? The ruling he made.
