One of the best cards ever. I use it as well as polymerization in a deck that also has invoked, because it has synergy with other fusions, and you can recycle the materials with Invocation, as well as searching for Poly with king of swamp, using this card as material for Invoked Cocytus

This card is sooo good and always will be. I recommend everyone to get 3 of them

Nah, it's definitely good enough to be UR. Fusion Sage, on the other hand, should have been SR or R from the get go.

Wish this card would be just a SR, it's not that great... it's even useful in farming decks.

Is there a card comming how is better for a fusion deck? Im really considering to buy this pack. But maybe it would be a waste if there will be a futue pack that would be better.

There is no other card that does what King of the Swamp does. (Be both a Polymerization and a Fusion sub.)

As just general Fusion support... I doubt we'll get anything that makes King of the Swamp obsolete any time soon. Unless they release Keeper of Dragonic Magic, but King's versatile enough that even that wouldn't likely make King of the Swamp not worth using.

Was this card erratad?
Because the text in the above picture does not contain the words "... whose name is specifically listed", while the additional text is present in the game version of the card and on sites like yugiohwiki.
It might seem like a small difference, but it's really not. It means that it can't replace a generic fusion material, only specific monster material listed on the fusion monster.

Fusion substitutes have always only been able to replace named materials. No wording change has ever changed the functionality of any of them.

Never in the history of the game have you been able to, for example, use King of the Swamp as one of the Dragons for Five-Headed Dragon, unless it's a Dragon-Type itself.
^^
I think this one should be just a SR :v
