Can you use king of the swamp for a contact Fusion?

Question

I just got a King of the Swamp card today and I was wondering if you can use him to contact fuse with E-Hero Neos?Can I fuse them?

Answer 1

Sorry, but no, no fusion substitue monster will work in a contact fusion whether it is for a Neo Hero or a Gladiator Beast. The problem is that the every Contact Fusion Monster say in it's summon requirement to return the above fusion matierial monsters to your deck from the field, unfortunatly this means that even though Fusion Substitues can be sent for most fusions, for these the Fusion Material Monsters must either BE the monsters in question or COUNT as the monsters in question. And when I say count I mean it's NAME has to change somehow to that of one of the above fusion material monsters. The only 2 monsters that can be used to substitute in a Contact Fusion are Elemental Hero Prisma and Phantom of Chaos, because their effects change their card name.
