Disclaimer: I will not focus on Art or grammar, unless the latter would make the deck too difficult to understand.
Alright then! "Pulling Majestic Dragon" jokes personified in Pyke Xiang's entire shtick, huh.
I like Dragons and Dragon decks, and I own up to that. And I like the idea of Pyke essentially having a Dragon for every significant duel she has had. That is excellent storytelling gimmick too, and a perfect way to add to the storytelling of a campaign involved. For the most part, the deck also looks like a good challenge, without being too much on its own? Even Sovereign Emperor Dragon seems to enter that category where instead of anything targeting, you just bust out "Nuke the Field" card types for it. I also genuinely love Dragonrider's Pike and how it functions. Funnily enough, the card I'm most on-the-fence about is Unbreakable Spirit Countering Counters and being repeatable without using your Power Card Moves at all, but even then I can kinda see it being a thing for the Champion, and it does have a cost involved.
Now, on the flipside... While I like the storytelling gimmick by itself, it happening in the middle of the duel rubs me the wrong way? For example, Majestic Dragon in 5D's is meant to be a big, epic moment, but it still does kind of deserve some of the jokes involved. And becoming a Champion for the public, while more or less cheating by spawning an entire new card per duel specifically for the opponents's gimmick, just feels off. If she instead essentially created the card during the duel and gained it afterwards to memorize it all? That'd be honestly brilliant. But as is?
Still, dragons. Good job!
