Need cards suggestion for Brudiclad

Hello! I’ve gotten a friend interested in mtg recently and figured building him a deck would be more efficient than getting a precon and so he wanted to have me make a base for him.

I’m brewing a [[Brudiclad, Telchor Engineer]] for him. He wants it to be relatively budget and “head scratching for opponents”.

If you’ve got any recommendations let me know! I’m experienced with artifacts and go wide decks but I’ve not played with something like his ability to turn tokens into copies of each other.

The prompt was for it to be win by numbers/go wide, head scratching. He wanted Zerg rushy kinda deck but told him that it might be less so with this commander but he’s good with that.

TLDR: give me some cool cards to put in a budget Brudiclad deck!
