Natural Gift should set off the Unburden boost, correct? In which case you could try:
Drifblim @ Salac Berry (80 BP Fighting)
Unburden
Natural Gift
Shadow Ball / Recycle
Stockpile
Baton Pass
Natural Gift gives you a fighting move that should catch would-be Dark counters off guard, and it gives you a speed boost to boot. From there, Stockpile up defenses to BP them away. Shadow Ball gives you a counter to other ghosts (good luck with that, though), while Recycle lets you try NG Fighting again or get a speed boost that can be passed.
