Notes & Combos
Going second with this goofy grass deck is really fun! I managed to get 15-0 with this deck and I don't even know how (I might play more to grind for more gems). Also yes, this is a going second deck. You can still play with it if you go first but you'd be better off breaking boards.
Apparently, most decks in this event are very weak to board breakers which I really didn't expect but hey, that works for those who want to go second. This deck doesn't guarantee an OTK but you want to get rid of your opponent's resources as much as possible and surprisingly, even if this deck bricks a lot, it manages to get the job done. And if you know your basic Shark lines and combos, you can end on a decent board even if your hand isn't very good.
Playing without Dugares feels a little weird as it's normally our best option to get to Armor Fortress. What you can do is go for Honor ARK and then detach all materials to attach 1 face-up attack-position monster your opponent controls that was special summoned and then Xyz Summon for Armor Fortress. This works well if you both don't have Armor Xyz and Full Armor Xyz. But if you have one of them in your hand, you won't be able to use Full Armor Xyz to rank up any further. You can also go for Dweller if your opponent doesn't control a monster then detach 1 material from it so you have 1 less material for Armor Fortress.
Since Ash is banned, you can safely play Beautunaful Princess, as it also dodges Imperm. You won't also be too scared to activate Grass, Thurst, or Talent. And speaking of Grass, it's the main gimmick of this deck so if you get your hands on it, use it. You get a lot of resources with a lot of your cards in the Graveyard.
You can change some of the main deck cards I used to make your build more consistent and less bricky or use other board breaker cards like Dark Ruler or use different amounts of cards like playing two or three Lightning Storm, it's really your choice as I'm playing with what I have. You can also change some of the Extra Deck cards like Xyz Armor Torpedo, Utopic Ray Lancer, and the 103 package as I barely used them. You can go for the Kragen Spawns or something else if you like.
