You can substitute this card for any 1 Fusion Material Monster, but the other Fusion Material Monster(s) must be correct. You can discard this card to the Graveyard: Add 1 "Polymerization" from your Deck to your hand.
King of the Swamp can only substitute for SPECIFIC fusion materials. Things like "an ojama monster" or "any dragon type monster" are non-specific. This restriction applies to all the wild card fusion materials like Goddess with the Third Eye, Mystical Sheep, etc.
But i like playing with extra deck... all-in and have 3 copies of it.
No regret!! now i can have fusion & synchro monsters in my extra deck!

Does nobody care about the artwork? Like is he shooting a laser from his head or he got shoot to the head? If he shoot laser, what he shoot at? The moon? And what's up with his hands? Did his hand broke? And is it he or she?
Great deck, I'd add one Fusion Recycling Plant in it.
Hi, i'm quite new to the game.
In my deck i've put the Arcana Knight (plus the 3 fusion material needed and polymersation card), but when i try to fusion 2 of them with the king of the swamp, i cant activate the polymerisation card except when i have all three knights, and when i have all three, i can't substitute any of them with king of the swamp.
Any idea of what i'm missing/doing wrong ?
It's because Arkana Night says "A Fusion Summon of this card can only be done with the above Fusion Material Monsters." This means that you can't use fusion substitute monsters for it and you have to use the 3 knights
