Fast shark XYZ that will crumble under the weight of a single handtrap. Main deck lacks handtraps because they are expensive. I've been playing a version of this deck with handtraps in Master Duel and it works well enough.
Starters: Beautunaful Princess, Buzzsaw Shark, Lantern Shark
Boss monsters: Utopic Draco Future, Silent Honor ARK, Silent Honor DARK, Stealth Kragen
Usually I summon Bahamut Shark and detach to summon Toadally Awesome for that toadally sick negate. If I'm lucky enough I can get out another Rank 4, then I use the two Rank 4s to summon Utopic Future -> Utopic Draco Future. If you're holding XYZ Remora in your starting hand don't detach, special summon Remora and then you'll get back the two detached monsters.
Set Whitefish Salvage as soon as you get it. You win if it's destroyed (add fish from deck to hand) and you win if it stays on the field (add fish from GY to hand every turn). Remember to special summon Silent Sea Nettle from your hand BEFORE special summoning Silent Angler. If you hold XYZ Revive Splash, probably set it.
After getting Utopic Draco Future out, I usually get out No. 4 Stealth Kragen if I'm in good shape, or No. 101 Silent Honor ARK if I'm in bad shape.
Sphere Kuriboh is the only handtrap you'll ever need.
