Jaden Yuki (Judai Yuki in JP) is the main protagonist in Yu-Gi-Oh! GX, the second anime in the Yu-Gi-Oh! series. While there are no images of Jaden in the game files just yet, there are certain leaks and rumors with his name available. He will most likely be an unlockable character when Duel Links decides to expand to the shows' sequels.
Is Jaden confirmed?
A recent datamined image shows Jaden Yuki's cards and how to obtain them. Click the blue button below for more information!
In the anime/manga, Judai uses elemental HERO deck. They are very focused on fusion summoning. Using Elemental HERO Neos, a level 7 normal monster and also his main signature card, it can fuse into more than 10 different fusion monsters using other elemental/hero monster cards, above are some examples of it.

His other potential signature card is Yubel. A main antagonist in one of the show's arcs, but later became part of Jaden by fusing together, resulting in a similar relationship like Yami Yugi is to Yugi Muto. Yubel is also an archetype, having multiple supports and revolves around destroying Yubel to be able to summon other monsters.
IDK how you can argue this. GX was basically OG yu gi oh. No synchros, no XYZ. Like they legit even had their own set of God cards in GX. No need to worry. I think it'll be dope to introduce E and Destiny Heroes into the meta.
Adding Miracle Fusion to your hand from outside of your deck could be a good skill, provided there's no other way to obtain Miracle Fusion. If they do make Miracle Fusion a pack/level-up/duel reward card, though, then Balance or Restart will still be better.
