Second runthrough:
I'm at the eighth gym right now, Team of Darmanitan/Archeops/Maractus/Klang/Siglyph/Scrafty.
Darumakka is horribly overated, hustle is a NIGHTMARE and makes it totally unreliable, but It's awesome once it evolves. Good moves from level 30+ especially but getting it there can be a challenge.
Archeops is the epitome of a glass cannon, it 1-2hkos the whole game with Acrobat above 50%, but below that there are issues.
Maractus is incredible so far. Once it gets Giga drain at I think lvl26 it solo'd half of elesa's gym, not even being 2hkoed with ariel ace and then healing back up. It also beat almost all of clay's gym on its own, though It didn't do much in the flying one. One you get Petal Dance at 38 it basically comes down to whether they can kill you before you attack if they don't resist. REALLY pleased with the cactus. Plus acupressure is fun.
Klang was a pain to evolve at first but Gear Grind is a really nice move and once it evolves it has considerable power. Steel type is always nice too.
Siglyph is very consitent, it does a good job of denting just about everything. mostly 2hko's though. It has good speed even though mine relaxed, to.
Finally, we come to scrafty. OMG Moxie! Ridiculous ability. Hi-jump kick at 31 is always nice, and free boost for killing stuff is awesome. It is slow though, so try to avoid flying types.
