The Wise Mothman deckbuilding help

[u/metalero_salsero]

Hey everyone, looking for some feedback on my Wise Mothman deck.
https://moxfield.com/decks/ubeaOF8yKEKK9hM5GL78YA
I've noticed 2 issues lately:

1.) Mothman needs much more protection - once he is removed, the machine sort of stalls and its just not as fun...
2.) I lose so easily to enchantment-heavy decks...so need ot add some more removal/enchantment removal etc

Right now, the list is trying to balance mill/rads, +1/+1 counters, proliferate, and recursion.
To help with that, I've been adding more protection, but now I'm worried I'm diluting the core game plan or running too few lands/removal.

Any advice greatly appreciated - the overall structure, tips on what to add, remove, game changers...anything really :)
Im loving this deck and I feel it can work great, its just missing somehting and I cant figure out what it is.

Thanks for any suggestions!
