I know youve already used mega chomp z but I made this team with scarf head smash terrak and t spikes amoonguss which are fun new toys they have, and its been working out ok on the ladder (total record was maybe like 10-2 on mid ladder, but i dont really remember since i was most just messing around with it for fun).
Standard chomp z and banded genesect sets, scarf terrak with eq for ghold and heavy slam for clef, starmie is there for hazard control but if you feel you dont need it then slowbro also works in that slot, spdef heatran with roar for stopping setup and racking up hazard damage, phys def rocky helmet amoonguss has 3 atks although its moveset feels very flexible so the other 3 moves can be whatever works best for you
