I've made it to Spinel Town, and have this as my current team:
Lv. 44 Hasty Swalot, Sticky Hold (Holding Poison Barb)
Strength
Yawn
Amnesia (Planned to replace it with Stockpile
Sludge
Lv. 44 Modest Ampharos, Static (Holding Zap Plate)
Take Down
Power Gem
Thunder Wave
Discharge
Lv. 45 Docile Arcanine, Flash Fire (No item)
Flare Blitz
Outrage
Flamethrower
Crunch
Lv. 46 Lax Exploud, Scrappy (No Item)
Boomburst
Supersonic
Shadow Ball
Rock Smash
Lv. 46 Mild Noctowl, Keen Eye (No Item)
Air Slash
Uproar
Reflect
Extrasensory
Lv 48 Brave Torterra, Shell Armor (Holding Miracle Seed)
Razor Leaf
Leech Seed
Curse
Earthquake
What I wanted to do was add a fighting type in there, but I don't know who to replace it with. I considered Swalot, but he's really usefull with poison and sleep.
I also want to get the Darumaka from Apophyll Academy for the really powerful Flare Blitz and some other fighting type moves, but I don't know if I should replace him for Arcanine.
