What I did, is I taught my Feraligatr Headbut from Ilex forest, and trying to get flinch-hax. You could teach headbut to Typhlosion, but since it's weak against water, I'd suggest you teach it to Quagsire

whats ur team?

beside what i mentioned above i have ampharos, jumpluff, togetic and pidgeot

it's terribly unbalanced but i wanted to do a run through with a few of my favorites

they've done fairly well up until this point

no shame in that, but honestly pidgeott is gonna be ur weakest link in this one, its stats are solid, but not great and is only good for flying type moves and normal, meaning brave bird or fly are ur go to attacks. the easiest solution and longest lasting investment is a piloswine or mamoswine

pidgeots actually done the best out of them all(since it's weaker than unfezant that isn't saying a lot)

ill give this a go, piloswine needs ancient power to evolve i think, now to find a suitable swinub

yup, gotta have the move tutor make him remember it, piloswine doesnt learn it.

and remember to evolve that togetic, but only once u like its moveset. togekiss is a monster

Catch a Mareep and raise to a high level and wreck Kingdra's SHIT, after that I think you can handle.

If anything catch a shuckle and raise that to level 45, at that point just use it as a buffer and to lower stats,

dude toxic protect rest bug bite
works pretty well when i toyed with shuckle

I used a Gyarados at Lv. 35 with Avalanche for her dumb effing Dragonairs, and a Victreebell at lvl. 37 to wipe out the others. BEST OF LUCK. You'll need the Gyarados for the elite Four Champ, too... he's a dragon bitch.
