>Torterra>Bibarel>Pachirisu>Floatzel>Drifblim>BastidionI purposefully made a team only of untiered pokemon to make the game harder. All of their nature's are bad and I have paid zero attention to EVs / IVs. Levels were 57-63, so a little under leveled.
Let yourself use a full restore or maybe even two during the battle to match Cynthia, that makes it fair. Then don't play like an idiot and you should be fine. Garchomp is terrifying, I should have brought an ice type move.
