My question involves the card Super Polymerization. I understand that it can be used to fusion summon using monsters on either side of the field, but it seems unclear on if those monsters have to be the ones listed on the fusion monster.
Super polymerization stats
Discard 1 card, Fusion Summon 1 Fusion Monster from your Extra Deck, using monsters from either side of the field as Fusion Materials. Cards and effects cannot be activated in response to this card's activation.
Does that translate to the opponent has 3 random monsters that I take to summon Blue Eyes Ultimate without any Blue Eyes? Or does my opponent need to actually have a Blue Eyes for me to use?
