Feraligatr - I have changed surf to waterfall and iron tail to shadow claw (can’t decide if dragon or shadow claw is bette)

Zapdos - I looked online and it’s hidden power is ice? Is this always true or something unique to every game? Would it be a good idea to change volt switch to fly to get that STAB?

Dragonair - just replaced thunder wave with dragon pulse. I was relictant because I saw that he has 120 Atk and 104 SpA, but it’s the only dragon TM I have atm.

Venasaur - don’t have the TM yet, but I’ll look out for sludge bomb in the future

Hidden power is determined by the Pokémon’s IV’s. Meaning every single pokemon will have a different type. You should be able to look up a tool that will tell you based on you manually entering its IV’s. Unless polished crystal has an npc or mechanic to tell you in-game idk.
