After a lot of struggle, I got it:
This was my top five hardest solos ever. Having 5 shadow dragons and Mega-Latios BARELY gave me the edge in order to achieve it. That been said, I’ve underestimated Mega-Latios. He was the real MVP of the solo. Being able to endure 65 seconds as my last pokemon and also being able to deplete the rest of Mega-Zard X’s HP makes him an amazing Mega sporting great DPS and bulk.
10/10 I wouldn’t try it again. I’ve lost 10 raid passes LMAO
