Thanks guys, was stuck on this for so long.

The rhino is a guaranteed win no matter what you do.

The Devildog Chameleon portion seems to work as follows:

1.) Select Dog,

2.) Round one: use skill 2 immediately

3.) Round two Use skill 1

4.) Round three use skill 2 (dog should faint, if your hp drops under 8k, or if dog is still alive... back out and try again)

5:) Select Chameleon

6.) Rinse repeat method for dog,

-Notes-

Suggested Power for the actual fights is 34k, If your team is exceptional you may get away with pow as low as 28k. Be sure to have a poison wind and ignite on bench or in team just for sanity as the actual fights seem to almost require their use across the multiple fights.

-@Rika the mystery glitch seems to happen if your connection is having issues, as in if you hit a key multiple times during lag it registers the most recent which may be the last action of a round (not 100% sure but it seems as much)

-edit- It is possible to get through the first portion with only skill 2, however I note this method as it has consistently worked for me.
