>>19913761Stall players don't use Blissey, they use Chansey. And Chansey, as good as it is, is also hilariously exploitable, being very prone to Bisharp (it absolutely can't afford to stay in,) being set-up bait for a lot of things, and being ridiculously easy to pull a double switch off of.
e.g. have special attacker out, switch in Mawile as they switch to Chansey, Swords Dance, and now something on their team dies.
Quagsire is also barely a catch-all physical wall. It walls a number of very specific threats. Same with Venusaur: there's really no reason to use it over Amoonguss, and it loses to quite a number of things.
