I'm not sure if this is a troll card or not. How many fusion monster exist, that would get a benefit from having to discard 1 Poly to get the fusion material out? Especially with losing 3/4 cards(1 Poly, this card, the material/fusion monster).
Fusion monster send to the graveyard with this card CAN'T be SS as they weren't properly fusion summoned first. And for BWD you have way better methods to summon it(Kaibaman, Kidmodo etc.) that don't need as much cards as this.
