Politoed only really helps thundurus(not really, therian enjoys rain more), and it doesn't really even help any other team member. If you want a water type, use something like rotom-w etc. first of all, lucario is not even common in vgc and if it is there, most carry espeed. cb is rarely seen on meta, hammer arm is almost never present either. Thundurus thunder should be calced so that it's ALWAYS a 2HKO. That ~2% could come back to haunt you. Also, now that thundurus-t is allowed, thundurus-I almost never had thunder. I would try calcing more common moves such as dgem meteor/fgem cc/ttar crunch/terrakion cc/thundurus-t thunder(bolt)/ chomp eq etc. on meta, something like 36 speed EVs help speed creep but you also could go lum berry + swagger and change the spread to 252 HP / 252 Atk / 4 def which makes it so you're never OHKOed by +2 (swagger boost) Metagross EQs or 3HKOed by regular 252 Atk Metagross EQs and is better imo. Also, PUT SWAGGER ON CRESS AND THUNDURUS. That is a must if you want meta to be more effective. You could even try it on p2. Also, maybe try safeguard on cress so you could also boost top without having it carry a berry. Plus, most of your team doesn't enjoy burn/para.
