Pretty simple deck mechanic here. Take away opponent's monsters with Kaijus, and use the Yosenjus to get your Kaiju back (Yosenju 1) or beat over it with an extra deck monster. Yosenjus come back to hand after normal summon, so it's a good idea to have back row protection and interruptions. There are a bunch of different cards to use and it's pretty easy to stay on the cheaper side. I have two droplets hence why there are two in there, but you can easily replace those with anything else. You can also interchange the traps (most people wouldn't play SMF, but I like it for the return). Side deck is also very interchangeable of course for whatever the meta is, and I would even have some back row disruptors possibly in there (Harpie's FD, TT, etc).
