Ok, that wasn't clear. Thank you for clarifying. The thing that keeps many Pokemon from abuseing spore to its fullest of course, is the four moveslots. That said, I think that this reasoning is indeed valid.IMO, spore can be viably used on any pokemon that is not seen as magic bounce fodder. I think that the widespread availability of spore is what makes it broken. If the opponent doesn't switch a magic bouncer in as spore is used, something is going to be slept.
What I was saying is that spore provides an important check to many sweepers that otherwise might dominate, effectively balancing the metagame.When you say that spore is more dangerous to these sweepers because it can stop sweeps, this doesn't prove if sleep is broken or not. Saying that using a powerful technique can check that same technique makes the technique not broken doesn't make sense. Yes, prankster spore can stop sweeps, but doesn't this show how strong and centralizing spore is?
If they magic coat and you sprore, you've just crippled Gengar, this dealing with it in the same manner it would deal with them. While I see that you use the Deoxys to subpass to Gengar, in many situations, the opponent would be prepared to sleep you with their magic coat.My point is, once the opponent knows Gengar has spore, they are taking a huge risk not using magic coat. Yes, prediction goes both ways, but this only matters if Jirachi/Shuckle are able to deal with Gengar in the same manner that Gengar deals with them.
In regards to mold breaker spore, there are quite a few ways to get past it, although most of them are used with it in mind. This may indeed be over centralizing to the metagame. I would be more open to testing mold breaker spore than the traditional variety, anyway. You have a valid point, although I am not sure how valid those in charge of suspect testing will see it. I hope I helped you develop your argument.
