>>36077398Bug is pretty much the worst offensive type in the game, and 50 BP is barely anything, so it's not really beneficial. It should be used on beedrill since there aren't many other options, but it is barely a boon. Odds are the psychic type that matters (alakazam) will outspeed and kill beedrill with psychic anyways.
Beedrill only learns double team, and it's so frail you might not want to waste it on beedrill, swords dance would be better
