Oh, I just battled this guy. My internet had a hiccup and we couldn't finish our battle, but I had my Water Spout Blastoise and a Machamp left, while he only had Charizard left. I had asked for an OU battle, though, and he agreed.
Funny thing, when I got paralized by the Dunsparce, I was unable to make a move not because of a flinch, but because of being fully paralyzed (I had used agility previously, so I was faster than it, which was sad).
