Finally!!!! T3 Solo Success: Machamp with Dynamic Punch
On my lunch break today; I knew I had time for only 1 or 2 attempts (I only get 30 minutes and the gym is 5 minutes away). Somehow, it worked... the first time! My winning team:
Espeon - 2807 - 37 - C/FS
Espeon - 2694 - 36 - C/FS
Alakazam - 2643 - 35 - PC/FS
D'nites: Draco - 3422 - 39 - DT/H
Makara - 3117 - 33.5 - DT/H
Drakkina - 3184 - 33 - DT/H
This was my first Machamp attempt since Sept 30... just no opportunity. But since then, I have leveled up to 38 and had enough dust to power up my top counters past their breakpoints... and it made all the difference.
I had only 174 seconds, and my phone (Galaxy S5) is an older, slower one. Rejoining is therefore not an option and I had to make sure my last fighter made it; therefore, I dodged the CM (DP) 2 or 3 times when I was down to my second to last D'nite. Still, it came down to the wire... and the last few seconds.
But what a glorious feeling! I got 9 golden razz and 2 rare candy, nice rewards. And it was really fun.
My advice, if you have the same goal: Don't give up. I thought I didn't have a chance, although others made it sound so easy. Just keep trying, power up your counters, walk a good eevee for an(other) espeon, catch or evolve another 'Zam, and keep trying.
Good luck!

Nice, well done! I use the S5 mini myself, so I know exactly what you mean with older and slower... It took me a long time and a lot of stardust to solo machamp as well. My current team is very similar to yours, and I can solo any machamp moveset with it, so I think you should be able to manage the other movesets as well!
