I play on Dueling Nexus, and I was in the editor, adding Knightmare Unicorn and Knightmare Phoenix to the extra deck of the deck I was working on, when something caught my eye while I was typing. In Dueling Nexus, there is a little icon on the card if the card is TCG or OCG exclusive, Rush Duel exclusive, etc.. I wasn't typing particularly fast, so I saw an OCG icon pop up. Now, whenever I post a Deck (save this one), I try to test it a LOT. As long as I win a certain number of games and don't constantly get bricks, I'll be good with it. I have Knightmare Unicorn and Phoenix in my Extra Deck in a LOT of my decks, especially unpublished ones, because they're good generic Link Monsters. Point is, I see the different cards with kni, then knig, then knigh, (and so on and so forth), VERY often. So, I go check the new card out, and this archetype is what I was greeted with. I'm not sure when these guys got added to Dueling Nexus, but I hope I'm not late to the party. Usually, I would try to perfect a Deck before publishing it, but this Deck is a little more complicated than most, and one of the cards might be bugged. Here's my inital version of the deck. I might post a more Meta version later, if I can make it work.
