This deck is admittedly slightly suboptimal. If you wanted a more competitive variant, you would cut the parasaurmon for another weedmon and 3 redvegiemon, and you would drop the toropiamon for 2 cherrymon. I prefer to sacrifice a little bit of viability for flavor, but I include the more competitve version here as well so you can see it. The Shivamon is a bit player preference, if you don't like it, it's by no means integral to the deck's playstyle. I like that it's a nice big thing that draws a lot of your opponents resources into it because of how scary it can be long term, but with Hydramon some people like to instead play more control and swing super wide, up to you the viewer. maybe you like this deck, maybe you don't, but my hope is that it at least helps you figure out what you want yours to look like. Good luck out there!
