There are several options to remove Chansey the people who post here are just unable to abuse that kind of stuff.
I posted some viable things to neuter Chansey a few pages before, look it up!
Thankfully these people wont get voting rights.
You are quite the are quite the arrogant little guy, aren't you?
There are plenty of way to remove moody too. Taunt, haze, clear smog, 100% accurate moves, phasing, A faster poke, bad luck on part of the opponent, ect.
That didn't make Moody any less banworthy. Lets look at Blazeken:
Priority, Slobro, Suicune, Excadril in the sand, switching a ghost in on HJK, Sturdy Steelix, Flashfire Chandelure, lack of healing moves, ect.
Notice how most of the pokes and things here are not hard counters. Slobro gets mauled by the special version, Chandelure, loses to shadow claw, and all the other pokes cannot switch into blaze without taking serious damage or dying.
Chansey, on the other hand is a wall, and what makes banworthy is going to be
much diffrent then what would make a moody, Blazeken, or even something like Brightpoweder banworthy.
You claim you realize chansey is a wall, and unlike other banned pokes, will typically
not take out 2-3 or even a full team by herself. What makes chansey ridiculous is how much she can cripple your team, before she goes down. The amount of damage she can do is amazing, and some of its counters including Cobalion, and Scarf Heracross
do not like taking T-waves.
@Capefeather: Just to name some of the top UU usages:
Espeon, Slowbro, Jolteon, Zapdos, Zorark, togekiss, Slowbro, Celebi, Quagsire, the Nidos, Milotic, Some vairants of Suicune, Empoleon, Scarfed Abomasnow, Electross, Shayim (pending no Sp.d drops), I could keep going.
Out of all those, there are still more. Any vesion of speical Kyugem gets walled, although the rare physical version could be problematic.
Between T-Wave and Toxic, only the Nido family and Steelix can overcome both, and the Nidos are completely walled by Chansey.
Even some physical threats, such as donphan or crobat can't take down a chansey in 2 hits, and brave birding chansey hurts like something else, even with roost.
