I admit first of all, there are certain qualaties that make it Uber, like it's speed. But in OU Choice Scarves are not uncommon. And a TrickScarf to Deoxys-S would destroy it.
Deoxys-S also cannot survive in Ubers. Compared to Ubers, his stats are very small for the most part, causing him to be very frail in Ubers, and indeed, in Ubers he makes an ineffective lead, usually only getting only about 2 spikes layers, which can be ineffective in Ubers due to the presence of Rayquaza, Salamence, Giratina-O, Latios, Latias, and a few others that just completely avoid them.
I believe, and agree with the opinion Volteon made a while ago, simply bringing his idea back to us, that an all offensive Deoxys-S would certainly be OU, thanks to his sad stats for the most part. And it wouldn't be the first time we had a Pokemon with a variable Tier like that, Latias was in OU so long as it didn't have Soul Dew, which then it would be considered Uber.
And past that, it is incredibly fast, but Blissey can just last for hours and hours with it's HP stat and it's Special Defense. In fact, such a powerful wall in OU, but a simple, speedy pokemon with sad stats for the most part is Uber?
I know he was OU at some point, but when he began being used for support, he was Uber. But with Bronzong's ability to easily set up Screens, and overall nice survivability, he too is game breaking in OU. But the problem is, even with those screens, Deoxys-S still can't survive up to some of the pokemon in Ubers.
Deoxys-S is also fairly predictable. There isn't much it can do in Ubers except set up screens or lead. Palkia, Dialga, Giratina, Rayquaza, and even Heatran, who IS OU, can OHKO it, thanks to it's sad defense and HP.
In fact, it's base stats are; HP:50 Atk: 95 Def: 90 Sp. Atk: 95: Sp: Def: 90 Speed: 180, and 5/6 of those don't reach 100, which like Shaymin, Celebi, Jirachi and maybe more, beat it at. It's moves aren't powerful enough to wipe out whole teams like most Ubers, and a Scizor Bullet Punch, and alot of other priority moves would easily bring it down. Not to mention alot of strong OU pokemon can surive an attack and easily hit back and OHKO.
Discuss Deoxys: S and other pokemon you think were wrongully shopped to Ubers, or even put out into OU or NU, or UU or anything really. Post about pokemon you think should be sent to another tier. Just keep on the topic of Tiers. Please, please, please refrain from talking about Garchomp, he definitly is Uber because he just destroyed all of OU.
