Hi there. First: my english isn't the best. But i hope, someone can help me. I want a water-pkmn (no magikarp). Level can be low (from 1 up to 6 ...) I don't have much. But maybe against my level 9 Ponyta or level 10 Charmander? I also have 4.000 pokedollar. Maybe someone can give/sell me a water type pokemon. Thank you
