Help sorting down a Dimir Zombie deck and unifying the theme.

I'm trying a new deck for myself and unlike my others, Sarkhan, UR Giants, Tinybones, and Infernus, I'm spoiled for choice but in a bad way. I see potential but because I'm not a combo player, I'm having a hard time trying to figure out how many engine pieces I need here.

The core concept is to spit out a lot of tokens, drop some lords to get them swol, and send them sideways into my opponent with little regard for their health. So to start, I grabbed a ton of token generators (both single and repeatable), shoved some draw into it, some removal, and helmed it with Narfi for consistent lord/sac fodder.

The problem is that I'm around 140 cards and making more cuts feels dangerous. Each card synergize with the others, so yanking each one out feels like more of a loss than I'd have with my other EDH decks or even my brawls.

Is there a good guide for deck templating? Such as ten removal, ten recursion, ten lords, etc? Or is that highly dependent on the commander and type of deck?

I don't want to run a high tier deck with searches, fetches, and game changers; I like the goofy decks that feel fun to play. Looking at other's decks can help but I'm not confident that's a good enough starting point.
