Garchomp can use Earthquake against Sharpedo. It's not a contact move so you don't take Rough Skin damage. Unless it freezes you with Ice Fang, you should win.
In terms of order, I'd suggest Ice and Dark first. Weavile is pretty much game over for Garchomp and if you are going to lose, lose early so you can start a new streak sooner.
Got 199 with that, lost for a hypnosis poliwrath >_<Got just golden print at hall and still continuing with almost same garchomp at TRE:
170 streak*
Garchomp @ Focus sash
Jolly
252 Atk/Spe 6 HP
-Outrage
-Fire fang
-Earthquake
-Swords dance
BTW, gold prints at all except factory and arcade. I hate those two D:
edit: oh and jump I think your 3v3 Gallade would do pretty well in the hall.. I might try that out at some point.
that might save you once, but after you do 170 they are all at rank 10 so you WILL find one eventually.Regarding Garchomp's Weavile problem in the Battle Hall, I think there might be a way around it for the first 170.
When you take on the 50th battle, your choice is interrupted, and you have to take the ??? block, which is the Frontier Brain there. On my run, I picked Steel, a type I knew Garchomp could handle, but the Pokemon she sent out was Lickylicky. It still advanced the rank in Steel. So, if you did your Ice set 5th (or 9 of Ice the first time and then # 10 of set five is Ice) you could hold off seeing a Weavile on rank 10 possibly. Weavile might show up earlier though, but I think this is a good safegaurd.
Friendly warning about the tower, as it caught me out: Palmer's Cresselia now carries Signal Beam and will beat Tyranitar with it.
the first is, if i use lucario for the battle hall can i use a dif natured / dif eved lucario later on or must it be the exact same lucario each time?
and i heard that you can switch your movesets as well so would a lucario @ focus sash with sd / exspeed / cc / and alternating crunch / ice punch / bullet punch / thunderpunch be best? that way you dont get stopped randomly by gyarados or salamence. or am i misunderstanding this?
