Misplays all over the place. For deck 1; I will see how I can fit infantry #2 in my deck, as for the bubble combo, I am thinking of taking one out altogether, making the deck 40. The side and extra decks were missing a card because it's coded differently in launcher than in pro, so the card was removed from my extra and side deck when I transferred decks. I fixed that, but it didn't save properly. The original build ran tidal in the side and drago sack in the extra, and my edits to that were TKR in the side and another Leviathan dragon in the extra instead, to keep the decks TCG.
Deck 2 is another story. D.E.S. Croaking is a must at 3 in this deck because of how much the deck is able to meet it's conditions. The inferno reckless summon combo allows me to instantly use D.E.S. Croaking, and even if that doesn't happen, I can always summon 3 ronintoadin or 2 ronin and a dupe frog, to do the same thing. Mother Grizzly is in the deck because she's searchable by salvage, and can summon ANY monster directly from my deck, including my sea lancer, without tributes. This makes her an amazing option in the deck. Other than that, I don't remember the gachi play, but I rarely ever play him in attack mode just in case of battle faders. Your spellbook deck could easily have mained that card, so it made sense to me to take a more cautious approach.
