Elemental Knights

The Elemental Knights are an all Level 9 Fusion Monster Card Set, that can be Fusion Summoned by fusing 1 "Headless Knight" and 1 Level 6 or higher monster. They have quite low ATK and DEF for Level 9 monsters, but make up for that by having very strong and usefull effects. Their strengt mostly lies in their diversity as for the only thing that they have in commen wich each other is that they need "Headless Knight" to be Fusion Summoned. There are 6 different Elemental Knights, 1 for each Attribute (excluding Divine) and they seem to appose most commen use for that Attribute. (Like Silphan seems to appose the Lightsworns, a much used LIGHT only Meta.) Another advantege they have is that they have a not clearly specivied Fusion Materials, making Super Polymerization another Fusion option to run.

Playing Style
The Elemental Knights mostly resembles a Anti-Meta style with Fusion aspects, becouse most of the E-Knights is a anti-version of their Attribute's ussual archtype. (Silphan against Lightsworns and Fairies, Rioku against Ice Barrier and Swarming and Carnum against DAD.) Also using Super Polymerization to steal your opponent's Trump monsters and Summoning your own can work really demoralising to your opponent. You should also add "Knight of Justice" as "Headless Knight" replacement and to stop your opponent from Special Summoning.

Weaknesses
The main weakness of the E-Knights is that they are totaly relying on "Headless Knight" and "Knight of Justice" to be Fusion Summoned. And this style also assumes that your opponent is using a Meta Deck, if your opponent is using some other kind of stragety. Then the cards become almost usseless. Also comes that most of the E-Knight have higher ATK then DEF (except for Silphan), so they can easily be destroyed while they are attacking. And cannot be brought back from the Graveyard, thought to they only can be Fusion Summoned.
