Notes & Combos
No floodgates because floodgates suck. -1 golden droplet, -1 smiting storm, -1 dispelling cause it felt slightly bricky with three copies of those, replace with more ultimate slayer, terraforming and hand traps/runick allure if you wish. Only lost to towers turn 1 when I didn't have the kaiju in my deck and pend ftk however, I was reasonably lucky with my matchups even while going second most of the games in DL 19.
Also never used gravity controller.

nice idea with the draw muscle. i would recommend running a cyber stein and naturia beast and/or add a blackwing zephyros. zeph can bounce the field for more draws, it's good discard for hugin and can xyz with geri into bagooska, dugares or zood line into zeus. also you should run a linkuriboh for that destiny hero card and lost world. i would cut the ultimate slayer and kaiju's.

Love the zeph idea and was testing with night sword serpent as an alternative since I don't have zeph and it works pretty well as a back up plan or just for an extra fountain activation when I had an extra fountain but no spells. I don't have cyberstein and don't really want to craft him just for this deck and naturia exterio is basically a spell/trap floodgate disguised as a fusion monster. Slayer and kaijus have been useful for removing towers like arrival or spell and omni negates which have been quite useful so I'm not gonna cut them yet.
