The argument would be more sound if five of those threats
actually had the room and utility to use it. Chansey's never going to do anything to Gengar in the first place, Manaphy, Alakazam, and Clefable have no room at all, and even with the Eviolite off, the pink bastard is still bulky enough to tank multiple hits, so it's
not dead weight. 250 HP / 105 SpD is STILL bulky, no matter how you twist it, and it still has similar physical bulk to Blissey given a few off points.
Anyhow, we're done discussing chansey and blissey in this thread. Discussion can continue in their respective threads (
Like this one.)
