Deoxys-L seems like more of something that everyone would be tossing Toxic at, only to be met with another Pokemon or *gasp* Taunt from a base 90 Speed.
I decided to look at some of the damage calculations and I saw that most of them are a bit situational and just common sense:
Before I post anything else, note that these calculations were done with the assumption that Deoxys-L would switch into the attack or setup, which would be necessary to prove the Defense Characteristic under which they are listed.
So, Scizor can 2HKO a wall that doesn't resist Bullet Punch? That doesn't seem too amazing at all >_>. Besides, if Deoxys-L is smart enough to stay in on Scizor, wouldn't it have something to retaliate? Perhaps, maybe it could just Taunt Scizor, heal up damage from the unboosted Bullet Punches and Night Shade its health down? Besides, why isn't Scizor using X-Scissor instead? I mean, obivously, the Deoxys-L user is going to OHKO Scizor with something, anyway or... just setup a Reflect or something of that sort :s.
I didn't have Scizor using X-Scissor because that would obviously do more damage. The same could be said of CB U-turn and the like.
-Neutral 0 Atk Deoxys-L using Fire Punch on 0 HP / 0 Sp.Def Scizor: 176 Atk vs 236 Def & 281 HP (75 Base Power): 160 - 192 (56.94% - 68.33%)
-What is this? Scizor can actually outstall Deoxys-L by using Roost, provided that it outspeed it. Granted, Deoxys-L can run enough speed to outpace Scizor, but that detracts from its walling ability just to outrun this.
Again, it's not really amazaing that something with a very nice offense (with a STAB base 120 attack) can beat something with a very nice defense considering that it doesn't resist any of its moves.
Oh and by the way, it's a 0% chance of a 2HKO after Stealth Rock when factoring in Leftovers (on average without Leftovers, it's still a 0% chance >_>). With Pressure and Recover, Deoxys-L will just force Heatran out, giving it the advantage on something else.
As "unamazing" as it is, fact is that it still does a good chunk of health. Furthermore, although damage calculations are done at full health, odds are that if Deoxys-L takes minimal damage prior to coming in (say Sandstorm negates its Lefties recovery, or it came in on a weaker attack like ScarfRachi Iron Head) it will be 2HKOd.
Um... Jolly Salamence 2HKO's a 252/252 Impish Groudon with a +1 Life Orb Dragon Dance, I don't get your point here :(.
The point is that Deoxys-L is nearly OHKOd by a pokemon that is all too common today.
Once again, this isn't surprising (CB Crunch doesn't OHKO >_> anyway) seeing as how Lugia, Cresselia, Mewtwo, Mew, Deoxys-A... a lot of Ubers take massive damage from a CB Tyranitar's Crunch, should we move them down to OU, too since a 403 Attack + a Choice Band + a base 80 STAB, SE move kills or nearly kills them >_<.
The point about CB Crunch's usefulness in Ubers is rather moot due to the large amount of Psychics. For one thing, Cresselia isn't Uber. Second, its obvious that CB Crunch will OHKO Deoxys-A, with its paper defenses. The difference between the others, however, is that Lugia is basically the fastest wall in the game, can get rid of 3 of its weaknesses through Roost, is capable of phazing, and has some offensive power to speak of. Physical wall Mewtwo can Wisp + Reflect with its blistering speed, while Mew's (usable) movepool is so wide that it would be silly to include it in OU. Your rhetorical question isn't too well placed.
And... Deoxys-L can't Thunder Wave or Thunderbolt it?
-0 Sp.Atk Deoxys-L using Thunderbolt on 331 HP / 236 Sp.Def Gyarados: 176 Atk vs 236 Def & 331 HP (95 Base Power): 204 - 244 (61.63% - 73.72%)
Gyarados survives after Stealth Rock, which goes to show you how offensively weak Deoxys-L is.
What? Risky? Healing off a 3HKO is risky? ToxiStalling is risky? Switching in, spreading paralysis is risky? Using Ice Beam is risky?
-So which is it? Do you want Deoxys-L to set up entry hazards, ToxicStall (which fails miserably against steels), or paralyze? Moveslot syndrome hinders Deoxys-L's efficiency; as its been pointed out, you can use it to wall what you like, but that's about it.
Once again, Deoxys-L can do something back in the time it takes to switch in on a Nasty Plot or a Flamethrower. Toxic and Thunder Wave actually do their job at crippling Infernape. Hell, even Light Screen has some type of viability.
So Infernape just NPs until Toxic wears it down to Blaze range, and THEN it kills you. You mention Toxic and Thunder Wave as ways of countering threats quite often. Where do you plan to use all of the support options you keep emphasizing?
The same thing that applies for Pokemon who need to setup to 2HKO Deoxys-L applies to Lucario, too. Who's to say that Deoxys-L isn't planning to do something as it switches in? Who's also to say that Close Combat will even 2HKO? There's a really low chance of that happening, anyway.
-A really low chance?
-252 Atk Adamant LO Lucario using Close Combat on 304 HP / 460 Def Deoxys-L: 700 Atk vs 460 Def & 304 HP (120 Base Power): 127 - 150 (41.78% - 49.34%) That's an 83.83% chance with Stealth Rock; although it is just a 19.79% with Lefties factored in. I'd say that's a whole lot of damage for a resisted attack. And then you have forgotten about Crunch.
This is probabally the only thing that can win against Deoxys-L (considering that it doesn't run Thunder Wave) if Deoxys-L switches in on it. Remember that that base 90 Speed isn't anything to overlook, Metagross tends to not always run max Speed and Meteor Mash's accuracy is shakey to begin with.
Even if Deoxys-L chooses to run Thunder Wave, Meta doesn't really care because it operates slowly anyway. The 85% accuracy is offset by a 1 in 5 chance of an attack boost as well, if you want to throw that in there.
Exactly >_>. Without some type of setup, not much is getting past Deoxys-L's defenses.
This is Azelf using an unSTABed attack without a nature boost and before a Nasty Plot, and it is still taking off at least a 3rd of Deoxys-L's HP.
Ummmm... Deoxys-L can switch in, Recover off the 4HKO, Night Shade and repeat, or, it can just force a switch with Toxic.
Point for Deoxys-L.
Ummmm... Setup fodder? Toxic much? Night Shade and a Life Orb are also withering down Suicune's health >_>. Not only that, but, it's not even a 2HKO after the first Calm Mind.
That's actually a 62.92% chance of 2HKOing factoring in both Stealth Rock and Leftovers. Surf's 24 PP > Recover's 16 PP. If Deoxys-L chooses to Toxic, Taunt, etc, that could be it right there.
Why is this even up here?
So... every Modest Magenezone needs Choice Specs to beat this thing?
So that's another pokemon that Deoxys-L walls - big deal. It also has a Choice Scarf, so its sp.atk is unboosted.
Going back to Jolly DD LO Salamence, it's not that surprising if a Jolly, CB Flygon can 2HKO with Outrage (30% chance with Leftovers). Choice Scarf Flygon obviously wanted to be trapped while 3HKOing with Outrage... right?
The point was that even with a Scarf, Flygon is still getting a good 70% off of it should Deoxys-L try to switch in.
Again, a STAB, base 120 Attack coming off of a very nice offense doesn't surprise me at all >_>.
Actually, Jolly Mence with a LO has a significantly higher attack score, so 2HKO with Jolly and CB is pretty nice. Hell, Flygon manages a 73.31% 2HKO (including lefties and SR) with just EQ.
Like Metagross, CB Mamoswine can beat Deoxys-L one on one, but, once again, it's not really surprising >_>. Unless LO Mamo is guarenteed the 2HKO, I don't see this as a reason to push someone's vote towards Deoxys-L being tested for OU.
-Well there are quite a few pokemon with those high attack scores that are capable of taking down Deoxys-L. Mamoswine is great in its own right, providing a nice check vs. Salamence / Flygon / Latias with Ice Shard, 2HKOing every bulky water with EQ, being immune to both Hail and SS, and being immune to Thunder Wave.
Actually, with Latias now in OU, it's pretty much the most common Snorlax set. But the fact remains that Deoxys-L would stay in, not fearing a Crunch >_>.
Deoxys-L can stall Crunch all it wants, but Snorlax will just come back in later and pound away with STAB Returns.
Weavile isn't using Night Slash because...? Ice Punch just gets healed off like anything else and Deoxys-L is still alive.
-Night Slash takes it on, there you go. Weavile can 2HKO with nothing more than an expert belt.
Let's see, avoid a 3HKO with Recover, Night Shade, Light Screen, Toxic, Seismic Toss, setup some Spikes and Recover off the HP or, just setup some Calm Minds.
A 51.28% chance of being 2HKOd (factoring Lefties and Rocks) by Shadow Ball is never a good thing. Setting up Calm Minds is a terrible idea, since Deoxys-L is a mild threat at best with its meager Sp.Atk.
On average, Deoxys-L isn't 2HKO'd very easily by a Porygon-Z's Tri Attack with 20% of its HP gone. Actually, with Leftovers, it's really not much of a problem, considering that Deoxys-L actually has a reason to switch in >_>.
-Note that it's a scarf. P-Z can also NP on the switch, and its a wrap. Furthermore, the Scarf set (or a regular set for that matter) can take advantage of Dark Pulse's flinch chance, and Download P-Z can take Deoxys-L down with boosted Sp.A.
Okay, so, the last time I checked, Empoleon isn't really safe from Deoxys-L, even behind a Substitute. Taunt/Night Shade/Recover/Toxic (or Thunder Wave) is enough to beat it one on one. Deoxys-L already outspeeds Empoleon without any investment whatsoever and can just Taunt it, Night Shade, Recover and just juggle back and forth between Night Shade and Recover. In fact, with Pressure, Deoxys-L has no problem getting past Hydro Pump and Surf variants.

Okay, most of those situations you mentoned weren't really viable at all. Tyranitar and Metagross are mentioned as counters already, so, I see no point in having to mention them. Deoxys-L is also a Psychic type, of course dark and ghost moves are going to hurt it and it's not like it's going to be taking like 10% from a strong boosted attack. Then, you count in the possibility of Calm Mind with much more Defense and Speed investment and its array of moves to choose from like Grass Knot, Ice Beam, Shadow Ball, Psychic, Focus Blast, Hidden Power, Thunderbolt, Thunder and Psycho Boost, coming off a base 70 Special Attack... it really isn't weak or bad at all. Anyway, offensively, Deoxys-L is like Blissey without Serene Grace, so, I doubt Calm Mind would see much light >_>.
Deoxys-L fails to OHKO Gyarados with Thunderbolt even after Gyara has taken Stealth Rock damage. The same could be said of Fire Punch on Scizor. And as I've said before, Calm Mind sets just BARELY manage to 2HKO Blissey with Psychic (and that is with +6 and Modest). Blissey runs a little Sp.Def (like it has been doing), and Deoxys-L isn't an issue.
Deoxys-L also has a knack for supporting so much easier than most of OU. Stealth Rock, Spikes, Light Screen and Reflect are so much easier to setup from a base 90 Speed and with Taunt hindering the slower Toxic users and Breloom, Deoxys-L's supporting side would just be a lot for the OU metagame. Stall Teams also get a huge boost from Deoxys-L as it can prevent a lot of setup and provide excellent support as well.
I don't understand why people keep using a possible boost to stall as a negative point. Of course, Deoxys-L itself is highly prone to Taunt and Trick itself, which are both equally crippling.
