Forum:I'm abit confused with Chimeratech's OTK

I'm abit confused here. I have a Chimeratech Overdragon and thought about the future fusion idea to amp it with loads of attack points and have multiple attacks. BUT, it says in the text that when it is summoned, you have to destroy all other cards you control. So, future fusion is also destroyed. Doesn't that leave the whole idea useless at this point? Or is there something I'm missing?
