ARTICUNO!!!

If you have a fire set ember flame wheel ect as your set move then use smoke screen once everytime he starts dealing damege then keep on useing your set move smokescreen should be used every 3 to 5 turns
if you don't have a fire use your partner as your fire sorce and do the first thing

If you don't have a fire as a parnter or you find or buy sleep stun and blast seeds 5 maximum each and use them to your atvantege

Oh ya and also articono has about 500 -700 health and has
Powder wind== can freeze and deal damege to you and your parter
