This was the deck that I used today to get 8th place at my Local OTS store, beating Evil Twin Runick Spright and Marincess, losing to Kaiju Plunder Patroll and Orcust, and tying Lyrilusc Tri-Brigade.
Main Deck performed really well. Apart from Forbidden Droplet never really having any use, the Kaijus saved me in necessary situations such as Spright Carrot and Marincess Aqua Argonaut. One thing I do regret was never adding Called by the Grave, which cost me a 2-0 against Kaiju Plunder Patroll due to a Droll & Lock Bird hit both times. Otherwise, generally solid deck.
Extra Deck could be improved. Mekk-Knight Crusadia Avramax and I:P Masquerena saved me from losing against Marincess the 3rd game, however I never ended up XYZ Summoning Evilswarm Exciton Knight; would either change it for Bagooska or Knightmare Cerberus/Gryphon, maybe even ZEUS.
Side Deck, apart from not putting in Called By the Grave, was ok. I don't like using Lightning Storm because if you don't draw it your hand going second it ends up being a useless card. Twin Twisters and Harpie's Feather Duster are better because if you draw into them, you can use them without any real cost. I was considering putting in Bystials but abandoned the idea.
