Forum:Future Fusion's "Cost"

Another quick question. Someone once played MST in response to Future Fusion, saying that, if played like that, you don't get to dump your monsters. There's no ruling like that on the whole page, so I wanted to make sure it's not some weird Game Mechanic like Nomi and Semi-Nomi. Also, is sending the monsters a cost? IE: You get it even if the card is negated?
