Looked into some swordsoul numbers and went with these ratios because the deck is generally consistent this way. Synchro zone is a cool tech pick and there is a combo you can do wtih gravity collapse as well, but it costs too much space in the deck and is unsearchable. I am running an extra deck that is pretty wrym heavy obviously, but there are some nice choices like adamancipator and barrone. PeP is also a neat choice, but strategist Longyuan burns so it isn't very nice, but it is a great option for busting out of near losses and its a guilty pleasure to play. Summit allows for a lot of extensions when drawn so it is increadibly good for recovering and pushing advantage though its not that nice to draw multiple of. Same reason we are running a Vessel, if you draw Taia you can dump a card for him to get a token plus some tenyi banishment extensions. Heavenly dragon circle allows for playing through interuption, same with droplet. Abyss dragon is good in this format if your opponent sets up a fire king island or the labrynth field spell. Though if your opponent isn't playing any of those then Iris allows you to play a bit during your opponents turn, plus I pulled a 25th of her so I am partial.
Extra deck is kinda weird, I mentioned the non-wryms that I am playing, I think they work very well in this deck, but I am only playing 1 Sinister because a lot of FZire decks play the charmer and thats killer if your opponent gets him. If they are playing fire, Chengying is a good because against sword soul you have a bit of graveyard interuption, kinda, but he is also a water that can't be stolen, plus 10 plus the level 1 adhara goes into PeP. The yangzing cards are good for extending your plays and helping you win over the board state going second, like in Baxia's case. I decided to run an abyss dweller because a lab deck may be running D-barrier, plus if you can't get to a synchro for whatever reason it can do a number interupting your opponents graveyard plays with fire king and snake-eyes.
