it was really there for psychic and fire coverage, along with will-o-wisping
you also saw it had solar beam, so there's that
okay well magmortar does all those things 3x better. It's just not as fast.
It can learn psychic, flamethrower, thunderbolt, will o wisp, solarbeam etc etc
solarbeam is only really good with a sun team, i mean keeping a fire type in on a water type is a really risky move, especially if said water type can withstand your low special attack hit. Notice how ninetales' solar beam did not even bring my froslass to its sash.
