the first option of corrupting the field isn't a really good one. and the second isn't an option. because the field will only turn into burning field IF it's not raining. which it totally is during all the fights outside the house
so. yeah. that's a problem. now corresponding to moves
Delphox - shadow ball, psychic, flamethrower, dazzling gleam
piloswine - blizzard, ice shard, strength, rock smash
primarina - moonblast, icy wind, sing, sparkling aria
ribombee - draining kiss, bug buzz, dazzling gleam, nature power
shedinja - metal claw, shadow ball, struggle bug, shadow claw
togedemaru - zing zap, nuzzle, pin missle and spiky shield
that's my team. not sure if it's a good idea to get a fighting type considering the fact that there's 100% a fairy move with that "Nomos" of noel
