Well I used seaking till the end,and it was quite difficult. It was great when it learned waterfall,but after that with no good speed and def/spd it died quickly. But I really liked the horn drill,had scary luck with it and it decided many battles,pretty much the reason why I kept seaking
I used unfezant till around lvl 45 or so. It sucks that it has such a good att but no physical flying moves(not sure where to get aerial ace,so I had none),but the reason why I had it was super luck. The air cutter hits most of the time with crit and that helped a lot. Perhaps go with murkrow/honchkrow with super luck,that would be my suggestion.
