Finally claming platinum guts.

I tried this challenge to take a break from grinding, it was fun but sometimes it was brutal.
Here's the team I used:

I went back and forth on some movesets, like Donphan was originally offensive, then I went to def with knock tect but was lacking ice shard, so I went back to offensive but quickly realized SD Lucario is an autolose for this team so I had to go back to impish. Gyara was originally ddance but again, fighting types were a problem. The team is decent, I wouldn't recommend playing it (besides for this challenge) cause if you face SD scizor you basically autolose, maybe you can tech firefang on donphan for that but I'm addicted to protect (maybe unironically flamethrower on gyara). I also really liked protect on Registeel, I felt like he was so strong like this.
It feels a bit like cheating having done the challenge with Donphan, maybe I'll tackle it again in the future, but for now I'll take it.
