U shouldnt rly focus on dmg, this is my moveset:
Politoed @ Damp Rock
EVs: 132 HP / 216 Def / 160 SpD
IVs: 0 Atk
U cna export it if you want(I say this cuz ppl usually make it manually instead of copy paste for export).
The EVs spread helps it mantain alive through matches so it's rain dance is effective and can be used at it maximum potential, obv supposing you r gonna use a rain team. It's best teammates r:
-Swampert mega which in Rian is a bulky fast strong god
-Tornadus t which can use hurricane 110 spa STAB in rain with 100 acc, which with rain isn't the case
-thundurus t the same that Thor t but with thunder instead of hurric
-rain dishers such as ludicolo or Blastoise
-2 or 3 coverage pkmn that r grass/ground/fire/rock/ice.
Scald is for burn, toxic for crippling some pkmn in different ways, 4 xmpl steel types or phy attackers which have there dmg halved, and the best to burn: gliscor, if you burn it, you turn down all the gliscor strat and it is 50% useless, then protect gives you a free toxic turn that makes dmg grow(cuz poi dmg grow in each turn) and lastly Haze takes down pkmn that use stat modifiers such as mimikyu, Hawlucha with tapus(opop) or even pkmn like klanger that all use swords dnsce bad Hawlucha gets na enormous boos with tapus, although sceptile can do smthng like that
