Probably no one will see this but i wanted to post in case anyone needs advice. I restarted the game some months ago and i beat Terra some minutes ago. My team was Alakazam,Exeggutor,Braviary,Blaziken,Simipour,Walrein. All lvl 75. My main strategy was to use Whirlwing to kick out ??? Pokemon and then finished them with Exeggutor's Wood Hammer. Took care of Garchomp with Walrein's Blizzard. Hippowdon with Simipour's Surf (while holding a Splash Plate). If anyone wants to know anything else or if I should post details,inform me.
