Forum:Vanity's fiend vs future fusion

It's true that I CAN'T activate FUTURE FUSION while VANITY'S FIEND is face up on the field? (on the OCG you wouldn't be able to activate it if there is a face up STATUE BARRIER (and its blocking the respective atributte) or if KOAKI' MEIRU DRAGO is also face up on the field and the only fusion monsters are light and/or dark.

and in the case FUTURE FUSION can be activated on this case, the sending the material fusion monsters from the deck can acomplish or not?

thanks
