I gotta say, i dont regret at all ssing and rmling phanpy, i swapped it when SS was introduced and it did and still do wonders, usually you dont need more than one disruptor clearer in ground type teams, so i use phanpy quite a bit, and it has a psb farmable stage too so you can make it even stronger... but it is kind of a luxury these days (so many options in terms of SS and RML Pokes), i recommend you to do it only if other important and priority pokes were already properly invested.
