Ok that's pretty much our point though the two counters are completely different and you have no way of knowing what set its running so what are you supposed to run counters to both? Or just get lucky? And tran can wall it on the first switch in, but with the lack of recovery tran won't do the job for long. Especially with all the hazards that deoxys is putting up, which you also don't think is a problem
EDIT: Just expanding on that... If you have to run TWO counters to be able to deal with ONE mon, don't you think that's a bit much? Especially if those counters may not even be able to handle things like subseed or no guard grass whistle? Not that those are common, but skymin can run so many sets, you can't possibly stop them all, if any.
Do you think we need to ban Heracross? Heracross has no counters. doublade is 2hko'd by tough claws knock off. Intim zapdos is 2hko'd by stone edge, you are forced to bb w/ skarm which kills you, intim skarm has to do the same. Intim suicune is 2hko'd by skill link bullet seed and 3hkos with tough claws cc and suicune does nothing in return.
