first off pls don't post teams you just came up with here, at least try them on ps if possible
considering the team, one thing it has a problem with is being threatening from turn 1. your two main methods of speed control, cress and scarf chomp, are super passive: cress can be taunted or faked out, and scarf chomp is going to be forced out a lot because you get locked into a move.
you have no fake out, so barring scarf chomp something like koko can just go ham (and even then they can have intimidate to weaken eq). palkia and necro are good sweepers but without sufficient support they'll just get outsped every time.
the team is also relatively passive aside from the legends, with cress putting in no work because no helping hand, conk having a mediocre amount of power, amoonguss being shut down by taunt/terrain, and chomp being unusable in tr and not wanting to lock itself into any move.
chomp in general looks kind of weird on this team. it's a pretty bad mon compared to other fast stuff so i'm not sure what the justification to run it over something else is here.
