I think I would.
Specs/Scarf Glaceon... 145 sAtt and 80 base speedI would definitely play in a tournament. Sand and Sun get great boosts, surprised no ones mentioned Hail. Rotom-F is a monster with base 101 Speed and 120 Sp Atk and that great STAB combo. Kyurem joins to base 100 Speed tier group, with boosted Sp Atk and even better bulk. Rain is the only weather without much of an improvement. More thoughts and stuff later.
I'm not saying nothing will, but just that many won't. Pokemon in a sensitive Speed tier or with doubled stats like Azumaril will certainly get a bump, but where as NU and RU look like unstoppable tanks and offensive weather Pokemon, UU Pokemon will only be slightly better. I mean again, Raikou and Zapdos, monsters of UU, face competition from Galvantula who sports a Speed tier just a few under Raikou, a Sp Atk stat not much lower when you factor in the Thunder boost, a great secondary STAB and better movepool. If you want Electric nukes, Pikachu is stronger. Torndaus I looks like a success with better Speed and the banishment of Torny-T (that Hurricane looks painful), but I mean I don't see the majority of UU Pokemon becoming huge threats. Still, there could be hidden gems. I think the most likely UU Pokemon (after all this is only theory) to rise will be Fighting-types and Stallbreakers. The majority of Fighting-types are in OU and UU, so UU's will be the only ones with boosts. With all these bulky Pokemon, UU's great stallbreakers such as Crobat, Sableye, Togekiss, and Mew, could all see use, even without huge stat changes. In OU, I think Steel-types will see some serious usage. After all, many of these Pokemon fall because they can't break prevalent Steel-types. Heatran gets props for shutting down a large number of newly strengthen Normal-types, Hail Pokemon, and even Sun Pokemon. Opting for HP Ground opens Chlorophyll sweepers up to be walled by Ferrothorn, which also walls a lot of new things. It'll be interesting to see what stays and what goes. I've been rambling a ton, I promise I'll have some more coherent and planed posts when I have time to organize some serious theorymoning.A lot of UU pokemon really benefit from a jump in speed tier; Tornadus shoots up past the base 115s, for example, which is huge. Azumarill enjoys its attack boost, which is doubled by Huge Power, and a few other pokemon really enjoy speed boosts along with the marginal offense boosts.
Don't get me wrong, everything gets better, but I don't think the +5s help Victini out that much. 105 vs 100 is a mere 3.3% boost, not really that significant. The Speed boost is nice, but this tier looks to have some really inflated Speed tiers, I don't know what it outspeeds that's significant. Victini might get more usage, but I'd chalk that up to it performing well in the meta, and I'd say it'd do nearly as well with its 100 stats.Ace Emerald, Victini really appreciates the +5, getting even faster and hitting even harder with V-Create.
You know... I didn't even realize the effect of stat increases being linear until I started playing Tier Boost.Don't get me wrong, everything gets better, but I don't think the +5s help Victini out that much. 105 vs 100 is a mere 3.3% boost, not really that significant.

No, base stats don't transfer directly to stats. A 252 ev'd 31 iv'd base 100 has a stat of 299, while the same for 105 has a stat of 309. Divide 309 by 299, you get 1.033... which basically means that going from a stat of 299 to 309 is about a 3.3% boost.Isn't 105 vs 100, you know, a 5% boost?
Speaking of Swellow, what about the other Guts-like NU threat Zangoose?So far, tier shift has been going well, and there's one major threat that's gone overlooked in this thread:
Swellow
Sporting a now passable 100 base attack and a completely absurd base 140 speed, Swellow is remarkably devastating with its infamous Guts boosted STAB facade, sporting high enough speed to go Adamant and still outrun everything, making up for its slightly lackluster attack. Swellow is an incredibly devastating physical attacker.
I think it's a really cool example of a way the metagame has succeeded. An NU pokemon has become just... very frightening.
