A few days ago i uploaded a Bystial BA deck, and then after that, i tested it in ranked on YGO Omega and got my butt cheeks handed to me. This list at least got me a single game in ranked against a good Marincess deck (i'm ass at playing high-level Yugioh, its a skill issue), so it should fair better.
Basically, your immediate goals are to either make Dante or make your once per turn monster negate (Cicada King), set any traps in hand, and then preferably get out Rexterm on turn 2 so you can shut down your opponent's combo lines. If you can spam enough bodies on board, you can make Tri-Heart or Decode Talker. There's 3 Rexterm in the deck because Kshatri exists now, and once Arise-Heart comes out in the TCG, its gonna be really, REALLY annoying when your important extra deck cards get sent to the Shadow Realm on turn 1. You may adjust the side deck as necessary, but unless there's some techs i just don't know about (either that, or if Small World is just that good in this deck), idk if you'll need to mess with the main deck much.
I'll have a video out at some point later. If i can't edit this page when that's ready (the site bugs out sometimes), i'll have to delete and reupload this list.
