Thought Id come back and revisit this deck. Haven't really played Yu-Gi-Oh in a while, but this little patch should clear up a good part of the deck clutter that I experienced with it.
A really few really nice combos I discovered while play-testing.
You can summon 'Silent Wobby' to your opponents side of the field, and not only do you gain 2000 life-points, wobby also acts as fodder to start that kaiju brawl.
if you start with 'Owner's Seal in your hand, you can instead of Special Summoning two kaijus, summon 1 to your opponent's side of the field then retake control of it leaving your opponent theoretically defenseless.
In the current META due to 20 minute long combos that involve lots of tributing and discarding and effect activating getting 'Kyoutou Waterfront' out on the field is essential!
'Neo-Spacian Grand Mole' can make a pretty nifty loop combo, by tributing your opponents boss monster to summon a kaiju before sp. summoining your own and normal summoning 'Grand Mole', you can attack your opponent's kaiju with 'Grand Mole' and send it back to your hand leaving them without a boss monster, you can continue this loop almost infinitely.
KUMONGOUS. IS. IMPORTANT. negating your opponent's ability to activate effects and attack in this current META is the best thing you can do, it can and will cancel their combo's leaving them wide open. if you find yourself against an overly effect reliant deck such as sky-strikers, time lords or subterrors Kumongous can throw off their entrie strategy, and paired with Kyoutou Waterfront, is really self sustainable.
Be mindful when summoning Gameciel to your opponents side of the field. Yes, he is the weakest Kaiju monster stat wise but thats a balancing chip with him. If there are readily accesible kaiju counters while once you've summoned Gameicel its better to take him out first before going for any potentially game ending effects (like Dogoran's).
