This is the "vanilla" decklist: Rebuilding the deck is basically the usual process - remove ETB tapped lands, substitute in "better" aka typed duals, more basics (yes more, most precons have unnecessary non-basic duals, and then run cards like Kodama's Reach and Fertilid, such that they can quite easily run out of basics to search for.) Focus on the core aspects or the deck - getting +1/+1 counters out on small creatures and spreading them around, then leveraging the growth in +1/+1 counters via varied abilities to turn small creatures into big fatties
