The magnezone discussion does come down to whether or not trapping as a whole is uncompetitive: arena trap catches everything but flying types, ghost types, levitate and air balloon mons and that is considered too much trapping but magnet pull trapping just steels is considered not enough trapping to be broken. Suppose in gen 9 we get a mon that can trap two types, or maybe even three, where would we draw the line? How much trapping is enough to be considered uncompetitive?The recent discussion about Magnezone is kind of interesting, considering how it has done the exact same thing since Gen 4 and not many have complained about it before (correct me if I'm wrong).
Another question this poses is should we ban absolutely everything even mildly uncompetitive just for tiering philosophy's sake or would that be detrimental to the tier? To answer this question I think we should look to our previous tiering decisions, NDOU has a history of taking action on stuff thats been considered totally fine for many many years and even saw less than 1% usage in the tier. Arguements like " Whether these items are "problematic" shouldn't necessarily be the question here, rather whether they are "uncompetitive" or not" were brought up to justify banning stuff from the meta game that didnt even make the VR. Just cause weve had magnet pull as a ubiquitous element of the tier for so long without it being "problematic" doesnt mean it deserves to stay if its randomly deemed uncompetitive, the same standard weve used before should be applied fairly here to Magnezone despite it being more popular then Cloyster, if its uncompetitive it has to go.
