>>40103961This is base HGSS, yes?
I'd say your best bet is to level them up some more, at least to the level of Miltank. So 19.
Lemme see...
>Flaaffy might not be all too useful, but maybe Static will come in handy for crippling Miltank, but it'll have to be done twice due to the Lum Berry.>Spearow evolves at Lv. 20, so if you're OK with a minor bit of overleveling, you could get a Fearow. Otherwise idk, it kinda gets fucked by Rollout.>Oddish evolves at Lv. 21, so again if you're OK with overlevelling that's a possibility. Oddish's Powders will come in handy, very much so.>If you can spare the time, Togepi evolves with high friendship, although it gains a Rock weakness. Other than that, it's got stuff like Yawn, Sweet Kiss, or Encore. And don't forget about the powerful TMs in the shop, if you can spare the cash. Her Miltank's got Scrappy.>Drowzee is a weird one, I guess his Hypnoses could work if you're lucky, but other than that he won't work all too well.I assume you've faced some losses. Don't forget that there's Routes and the National Park open, so if you're good at MGS-ing past Trainers you could catch some solid lads.
