Because i wanna make a team with my starter, empoleon, and heliolisk and kabutops. Empoleon will have surf for STAB and rain boost, and will do little damage to kabutops assuming it doesnt miss thanks to the Detect Looplet. Then Heliolisk will Thunder everything, and kabutops will slice everything to death witg swift swim. Heliolisk will have Dry Skin for Rain and Surf.
Trouble is, they cant relearn rain dance, or be taught it for coina. Where can i get it/what other pokenon can i use?
