Use Steelix to deal the perfect amount of damage to get 2 or 3 Pawniards down to 10 health or 1 Pawniard with a Bravery Charm then hit very hard with a Bisharp. If your Bishharps or Pawniards die, get them back with Miriam or Super Rods. Use Artazon and Nest Balls to get lots of Pawniards quickly and use Manaphy to stop people from sniping your low-health Pawniards.
