Good for U! the moveset i reccommend would have to be
sky uppercut
spore(need to keep shrroomrish from evolving until it learns it, then evolve)
seed bomb(egg move, but if u don't wanna do breeding again, use rock slide)
bullet seed or swords dance(if using seed bomb, use swords dance, if not, use bullet seed)
if u want to do the breeding and get the egg move, i would reccomend the seed bomb because its physical and get STAB atk bonus, making base power 120, also go with swords dance if ur gonna use seed bomb, hope this helps:)
