The main idea of the deck is to spam out Dangers! and use the Pot and stuff in order to draw through your deck. The main boss monster is Thunder King, but it'll be nice to have a few other monsters out as well, like Bigfoot. I reccomend keeping around your normal summon, in case you want to tribute summon a Kaiju; but you can also tribute an opponent's monster to give them a Kaiju, to then special summon a Kaiju to your side of the field. But you can also use Interrupted Kaiju Slumber; there's many ways to get out Thunder King. There's also alternatives with the other Kaijus, in case you're having trouble with running into Thunder King.
The deck is very aggresive and focused on OTKing the opponent, by immediately lowering them to 0 as soon as possible. I reccomend going for second, but going first isn't super bad; just be wary of removal, as the deck can be fragile.
Note: The side deck is just for match-ups against certain types of decks, like a deck that runs all spellcasters or insects, and the extra deck is just a mix of good targets for Maximus. With Maxiumus, you'll want to toss out N'tss to remove the opponent's monsters, (Skull Knight serves the same purpose), and Psy-Framelord Omega for a purpose I may or may not have forgotten. The other monsters in the extra deck are just monsters that I personally like; change them out as you like.
This is my first time posting here, so i'd love any feedback! Cheers.
