>>22434321Having few weaknesses is good but its not going break it into high grounds just like that, example for this is Spiritomb. Great defensive typing in ghost/dark, 3 immunities and one weakness
before fairy it had none obviously, its stats were passable as a tank but not outstanding thanks to its HP and its movepool is pitiful. If its movepool has more than ghost/dark, it would be better but a shallow movepool can hurt when you can only answer to so many things. Or Eelektross which is sort of the opposite, essentially no weakness with its ability and great movepool to abuse either attack stat with but its remaining stats don't make it fast enough to even outspeed some walls or its bulk being mediocre at best, meaning it wouldn't handle as many things as you would want. Not to say they're bad though, just what they have isnt enough.
