Reducing a Pokemon's movepool will undoubtably reduce the Pokemon's overall worth. So one may ask, if removing Draco Meteor and Outrage from Standard would place 4 suspects in to OU, could we not follow the same decision with other Uber Pokemon?
Arceus
Darkrai
Deoxys
Deoxys-E
Deoxys-F
Deoxys-L
Dialga
Garchomp
Giratina
Giratina-O
Groudon
Ho-Oh
Kyogre
Latios
Lugia
Manaphy
Mew
Mewtwo
Palkia
Rayquaza
Shaymin-S
Wobbuffet
Wynaut
From looking at just the base stats alone, Arceus, Darkrai, Deoxys, Deoxys-F, Deoxys-L, Dialga, Giratina, Giratina-O, Groudon, Ho-Oh, Kyogre, Lugia, Mewtwo, Palkia, Rayquaza, are all unfit for competitive Standard Play. Even assuming you took away signature moves, such as Darkrai's Dark Void, or Arceus's Judgement, or Palkia's Special Rend, or Ho-Oh's Sacred Fire, all of these threats are still capable of severely damaging the integrity of the OU meta.
Wobbuffet is banned exclusively due to its ability, Shadow Tag. And because we strive to replicate the cartridge, and thus cannot ban Shadow Tag exclusively, it also must remain in Uber. Wynaut is arguable due to significantly lower base stats, however that is a different can of worms I will not open, and it is for the sake of this discussion assumed to be under the same circumstances as Wobbuffet.
Mew is clearly banned because of it's unique ability to learn every TM, HM, and Tutor taught move in the game, resulting in a movepool that eclipses all but the likes of Smeargle. One could argue that banning an assortment of Mews moves could result it is inclusion in to OU, however because it is being established that a blanket ban would be used, this would result in a multitude of Pokemon being subjected to unnecessary removal of options. Clearly in the case of Mew, this is unreasonable.
Manaphy I am going to leave out of this as currently it is either being tested as a suspect and possibly going to be admitted in to OU, or it already is. Shoddy has yet to implement it's placement in to the OU ladder, but for this discussion I will ignore Manaphy for obvious reasons.
So what do we have left?
Deoxys-E
Garchomp
Latios
Shaymin-S
All of these Pokemon have impressive base stats, however, are not threatening enough alone by themselves. Unlike the previously mentioned Uber candidates, who all have at least one distinctively factoring reason for being placed in Ubers, these Pokemon have a plethora of reasons that, while by themselves do not amount to their Uber status, together ultimately led to their banishment.
I will now examine these Pokemon based on the assumption that the removal of key moves will result in their inclusion in to the OU environment:
Shaymin-S
I believe it is reasonable to assume that despite it's impressive Speed and Special Attack, it's inclusion in to Ubers is a combination of Seed Flare and Air Slash, and it's ability Serene Grace.
It is already been established that banned abilities goes against the policy of cartridge replication, so banned Seed Flare and Air Slash is the obvious choice in this case.
The problem here is that banning Seed Flare would result in a negative impact on Shaymin-O, and the banning of Air Slash would result in the negative impact on Togekiss, both of which rely on these moves to compete.
Deoxys-E
While I believe it is arguable that Deoxys-E itself is Uber based on it's Stats and Type, it's claim to fame was the infamous double screen set. This was based around the use of Light Clay + Reflect/Light Screen, and Taunt to stop leads and anti-leads.
While there is no specific Pokemon that rely on the use of Reflect/Light Screen (and possibly Taunt, I'm unsure about that), I do not feel it is reasonable for the exclusion of Double Screens as an option for many Pokemon that make it usable (Jirachi, Bronzong, Cresselia, et cetera) for the sake of bringing Deoxys-E in to OU. Removing Light Clay would only serve to weaken the underlying problem.
Garchomp/Latios
As you can clearly see, we have come down to the two Dragon types that arguably could contend appropriately in the OU environment without the use of Draco Meteor and Outrage.
While the exclusion of these moves may serve to open these Pokemon up to the OU environment, it is interesting to note that the banishment of these moves will not serve to leave any other Pokemon unusable outside of their current tier, as Dragon Pulse and Dragon Claw serve as adequate substitutions on the same sets. Admittedly these Pokemon will drop in use, but it will also allow for the inclusion of two current Ubers (potentially), and the possibly prevention of two other (publically opinionated) suspects, Latias and Salamence.
And unlike the banishment of moves from the reservoir of other Ubers, this will serve to only limit the Pokemon of the same Dragon type. Any non-Dragon type does not use either of these moves to compete competitively. Also, unlike the other Ubers, these Pokemon lack any distinctive criteria that makes the Uber without the inclusion of these moves themselves.
I know this all may serve to be self explanatory, but I thought it would give people some proper insight as to why banning moves until other Ubers are acceptable candidates in OU is not an argument with very solid ground. What we are witnessing here is an exception that may lead to a healthier meta. However the question is whether this will serve to open the door to the exclusion of moves in the future, and whether or not we know where to draw the line. But I'd like to believe we're a smart community, right?
