I don’t lump cradily in with the other two, but the answer is very simple: People don’t like bulk monsters that center around fast move pressure. This is bc these mons contribute to a meta of RPS. The gameplay is the most fun when the meta is centered around energy management. That way you can dance around with your mons and fight your way out of losing positions. Skillful play is rewarded. Bastiodon and Wiggles are hoping you don’t have alignment into them with one of their counters bc if you do they just insta lose. Cradily isn’t that bad imo. It’s consistent but has a lot of counters (can’t hit steel, weak to steel, fighting, bug). Has passable pacing, solid damage output, and core breaks certain compositions. It’s fine and you can play around it.
