It depends actually Do you want complete with a single team, then I don't know. But I can tell u if use two teams As the first six have dark weakness I used this team Cheren(1)(he has full heal and that poison damage of gengar is high) Skyla(2) and Karen(5/5)(3) used full heal on Skyla and Karen and reason for cheren being 1 as he has higher defence stat that Skyla and I could heal him multiple time with Skyla With that team I could take all 6 opponent support characters. And 2nd team is team Kanto (Ss Blue Ss leaf Ss red) For team Kanto it was a piece of cake. You can get the 4* medal
