Just so how Vylon, a completely F2P archetype made it to KOG as well, it's in the last page so I will post it here, I guess they won't mind.
Probably the most F2P deck in the current meta.
Oh Playmaker said that he was inspired by the idea of Duel Links C and that He was the original creator of this deck. Playmaker just wanted to make it popular because it was quite a marvelous idea.
