First of all change Meowstic's nature to Competitive. Hawlucha should wreck Hariyama, Mienshao and Conkeldurr if you send him out at the right time tbh. Get Thunder Wave on Magneton in place of either Metal Sound or Tri attack. Sturdy Thunder wave means you always get 2 turns before you die - in the first turn you use T. Wave after your opponent moves (as Magneton's speed is pretty low) then in the second you outspeed and get a free attack off and with good RNG you can even paralyze them for more turns. Remove Protective Pads as they are completely useless for him and give him a Thunder boosting item (Zap plate if you got one from mining, or Magnet, or a Weakness Policy if you have neither) and use him against Hawlucha and kill him with T.Wave + Discharge. Save Incineroar for his Lucario - send him out right then for Intimidate and break his Focus Sash with Fake out on first turn, then use Flare Blitz or Cross Chop to take him out. Alternatively send out Meowstic and use Fake Out to break Sash and then kill him with another mon after sacrificing Meowstic for healing or reviving turns on other mons. You can use your Seismitoad against Blaziken after swapping out a mon from your party (Heracross/Slurpuff/Amoongus).
