With Water and Frie Pok'emon:
Take me for example. I have a lvl 53 Swampert, lvl 14 Zigzagoon, lvl 26 Peliper, and, lvl 27 Ninetails, Absol, and Girrafirig. I just bought alot of Max Potions and Revives. If you have Lots of Fire-type, I'd consider buying ALOT of Revives & MAx Potions. Or, for water type, try to teach it Bullet Seed.
Hope it works!
