You can look for a mentor especially lvl 50 or more(they can lvl up disciples faster) and then ask him for plvl(lvl up)
Wallace (Gym Leader of Sootopolis) has: Ludvisc: lvl 40 Whiscash: lvl. 42 Sealeo: lvl. 40 Seaking: lvl. 42 Milotic: lvl. 43
I'd get rid of the Regirock, because you have a Groudon already, and get a Manectric.
carvana evolve in lvl 40 in sharpedo.
this is an impressive team i recommend getting registeel and regice a little stronger though.
no i could not beat him with lvl 69s but i beat him with a lvl 81
Ok, strategically your best lineup would be: Blaziken lvl 40+ Groudon lvl 50+ Salamence Lvl 65-70 Flygon lvl 70+ Wailord lvl 40+ Milotic lvl 50+
That's a great party, just train them to about lvl 60 and your ready to kick butt.
if your lvl 40 and above it's a piece of cake because the skill of lvl 40 and above are much stronger and also recruit lvl 40 or above friends.
till lvl 40
Alliance: Hinterlands Horde: Uldaman
