It's one of those streamer shitposts where a watcher pays $50-100 to add a card to the deck and he has to bring that abomination to an event.
The skeleton was probably just all the Dracotail core and Bystials, and he whored out the rest of the slots to the viewers.
This obviously makes him much more money than actually winning the tourny would so it's win-win for him.
Also noticed he went up to a 60 card maindeck to maximize the amount of cards (and money) he has.
