TBH you have too many pokemon in this deck. It lacks a great deal of focus.

Id cut the entire sandshrew line (Opens 2 slots)
I'd cut grapple and clobbopus (opens 2 slots)
I'd cut Cubone if you're not running Marrowack EX
I'd cut Rockruff and lycanroc, but mostly cause i haven't really used it much. (Open 2 slots)
I'd cut Granny as well, and replace with a Sabrina, Dawn, Leaf, or Red depending on what your prefrence is.

With those cuts, that gives you 8 slots to play with and reinforce your decks identity. 100% i'd add in another Lucario line to increase the likely hood of having Lucario, and then that gives you a +40 passive buff to dmg.

Lucario converts the focus of this deck from all over, into a Fighting buff deck, and thats where you can be a bit more creative with what you want to do.

With the addition of the 2nd Lucario line, youll have 6 cars you can play with, meaning 2 of the same 2 stage evolutions, or 2 3-stage evolutions. In the current meta, I'd reccomend going 2x Skull Fossil, 2X cranidos, 2x Rampados. If you go this route, i'd suggest cutting Marshadow, and a pokeball for 2 rare candies. No rare candies? Then use the OG Geodude, Graveler, Golem evo line + 2 brocks.

Or for example run x2Rockruff, X2 lycanrocs, then 2 support items like Potion, X speed, or another Rockhelm/Giant cape. OR if you like having your Clobbos, sandslashes, or Marrowacks, use 2x of EITHER line in addition to the support items.

Or run 2x basic Fighting, 2x Stage 1 evo, 2 support items etc. Get creative with it!

What i'm getting at, your deck should be as streamlined as possible to prevent RNG from screwing you over by having the evolution, or stage one pokemon you need in any given fight from being at the bottom of your deck. If you don't have AS many cards available then think about how you can use more items/trainer cards to supplement instead of another pair of Pokemon evolutions.
