Amphibious Burgoth and Fenrir would be cool too, especially Amphibious Burgoth because he can attack directly when umi/legendary ocean is on the field, and plus if you put gravity bind it became lv3 and literally nothing can stop it.
Good stuff man, really enjoying the meme decks! If I may offer an idea, I would love to see you experiment with the Element series of monsters (Element Saurus, Element Magician, Element Soldier, etc.) They aren't super good, but I have a lot of nostalgia for them, and you could run like Homunculus or something to make their effects live. Keep it up man!
Level limit was in the deck, though. Didn't want to bring it in, but it's certainly there. I think Ocean is still better than Umiruka here. It lets knight attack twice, which is the most aggressive thing you can do, outside of the Terrorking Salmon/Gogiga stuff, but that's so inconsistent. It also protects mona like Gagagigo and Tribe from Tsukuyomi. Also lets all your stuff stay in atk postion when level limit is out.
