change swamperts moveset to his one :
avelench-since swampert is a physical attacker
hammer arm\stone edge-all physical
waterfall-its STAB and its phyical
earthquake-super powerfull physical STAB
change arcanines movest to this one :
flare blitz\flamethrower-STAB (better level it up so it will lrn flare blitz for this echnique)
sunney day-arcanine is uick so its good for it to start things up and powers up this all thechnique
morning sun\thunder fang-morning sun is an egg ove so if you don't want to breeed again then go with thunder fang
solarbeam-no need to charge with morning sun
