Super fun, fairly consistent, and cheap deck for the Extra Zero event, we have my favorite archetype on full display. The U.A. playstyle of constantly switching out monsters with offensive capabilities with monsters with defensive capabilities after the battle phase allows for multiple plays depending on your starting hand. Some cards, like The Warrior Returning Alive, ROTA, Planet Pathfinder, and Terraforming are added to allow you to more consistently get your level 4 monsters in your hands and the field spells which allow you to get a decent amount of card advantage for normal summoning those level 4s. Witch's Strike has also been added to disrupt your opponent should any of your defense line monster's effects get negated, but you could also swap this out with backrow removal as I've found most decks don't run nearly as many negates as other formats. The best way to learn this deck is to play around with combos on your own, though if you need some tips to get started, you want to have as at least 2 of your level 4s in your hand as soon as possible, but if you have the option to create your starting offensive line (Mighty Slugger and Dreadnought Dunker are fantastic options for this), your starting defensive line (Block Backer and Perfect Ace are good choices for this), and your "waiting bench" line (These are cards whose effects activate/are most effective when summoned during your opponents turn, namely Player Manager for easy board control or Rival Rebounder for swarming), then you should get that set first and do everything to make sure you have at least 1 of your level 4s in hand by the end of your turn, or some way to protect it on the field or return it to the hand during your opponents turn. If you're having trouble getting over tricky monsters like Machina Ruinforce and the level 10 Floowandereeze, we run 3 U.A. Penalty Boxes for that exact reason. My current win/loss ratio with this current version during this event is 11/8, though the addition of Adventure or backrow destruction may help if you find yourself stuck often. Enjoy fantasy football as you've never played it before!
