Feeling like there is not enough of everything in my deck

Hello.

So recently, I decided to make a fun, casual commander deck focused around [[Runo Stromkirk // Krothuss, Lord of the Deep]] since he seemed like quite a fun and unique little fellow. Once I started brewing tho, I felt like I had a problem with balancing between the themes of the deck. Of course we all probably have this problem when making decks. There are so many cool cards and you can only use 99, but I felt like there simply was not enough of everything to make the deck consistsant. I am still new to making my own decks I wanted to ask for some help and advice.

So, obviously, the two main things are reanimator and big aquatic creatures that Runo will copy with his ability, so I need my big creatures to use with Runo, I need mill engines to put them in my graveyard, and things to bring them back with. Additionally, I might often be forced to play those big creatures from hand, since Runo requires the big creature to be on top of the deck to flip him, so I need ramp, also, top of the deck manipulation is useful to make the commander consistently flip early in the game when there are no big creatures in the graveyard. Then obvioisly I need interactions, board wipes, counter spells, removal and all that, so I can survive untill my big guys get on the board. Some cheaper creatures would also be nice so I don't sit open for X turns, trying to make everything work.

All in all, I feel like I can't put enough cards of each type to make the deck actually be consistsant in most of the games. Currently with this version I really feel like I lack interactions and mill the most, but i also feel like I could use a coupe more creatures, both big for Runo and small to protect myself. The only thing that I could see cutting a bit would be top of the deck manipulation cards, and maybe ramp.

In any case, I guess all i want is some feed back on the deck and advice on what changes may be needed to make the deck better.
