>>41102584Mew/Mantine/Pelipper are already stablished defoggers, and they will still fullfill that role
Flygon and Skuntank will find a place in the culled meta, particularly since levitate/poison typing allow them to ignore spikes and toxic spikes respectively
Togekiss and Whimsicott may give it a try but I don't see any space for them to use the move without cutting on better moves for their roles
Hawlucha and Hydreigon have better things to do, but the fact that they scare off others so easily may allow them to easily defog
Silvally is still shit, does Type Null learn defog? Corviknight will find space depending on learning some form of hazard, if it does then it will become a good defogger, otherwise it will just be nu Skarmory
