6 Rhydon take down a 10 tower

The gym: 2156 Blissey, 2385 Vape, 2399 Snorlax, 2489 D'nite, 2513 D'nite, 2519 Blissey, 2702 Rhydon, 2898 D'nite, 3003 Gary, 3131 Trex.

I had 9 in gyms already, so didn't have a lot to choose from for the attack. "Auto" chose 6 Rhydon, so I looked at it and only moved a couple around and went with it.
The Attack team: 2697 MS/EQ, 2425 RS/EQ, 2824 MS/SE, 2887 MS/EQ, 2949 MS/SE, and 2472 RS/EQ. (The 2 MS/SE are usually in gyms, but weren't today.)
I had my doubts about using nothing but Rhydon, but this was probably the best team I could put together. I dodged as much as I could, but did get hit by the Vape a couple of times, and by the Gary. I took the gym in the first run with about half of my health left on the last Rhydon!
Wasn't so lucky the second time around, got hit a few times early, and only beat 7. Kept at it though, and took that tower apart! I never fought a gym before using nothing but one type of attacker.
