Thanks Deck! Provided nobody else gives me constructive feedback, I will likely mark my spread as final soon. Now onto some comments of my own.
NOTE: This is only my personal feedback. If you disagree with it, then feel free to leave your spread as is.
Salt: I like this spread; it beats what we want and loses to what we want. Though I understand the reasoning behind 133 Sp. Attack, I fear that it may be crossing the threshold for this CAP simply turning into a Special nuke. It's up to you to decide how important it is to one-shot Mega Gardevoir.
P3DS: Your BSR is over the maximum limit, so this spread cannot be slated as is. Nonetheless, the 106 Speed is important to beat Mega Pinsir, but don't worry about Mienshao; it's not relevant in OU as of now. Some more time with the damage calculator would help you justify your Defense and Sp. Defense as well. Though you tell us that we live attacks such as Talonflame's Flare Blitz, you need to show us with the calculations.
srk1214: I'm actually not the biggest fan of losing to Landorus-I, as it often carries Focus Blast to mess with us if we Mega Evolve. The Speed tie with Mega Gardevoir is scary as well, as we want to dish out some damage before she can Psyshock/Psychic us. The Sp. Attack and the bulk both appear to be fine, though. I also like that all the stats are divisible by 5- though that does not affect the spread in any way, it is aesthetically-pleasing.
NumberCruncher: Instantly I can see that the Speed is too high. Remember that we want to lose to Greninja and Starmie, so outspeeding them is a no-no. The reasoning behind your low HP stat makes sense, as it encourages support from Gyarados' teammates, and I agree that we should lose to Chansey. I need to see more reasoning for the 90 Sp. Defense, though, as it appears your spread is one of, if not the, most specially frail so far. Also, Zapdos is not a hard counter, as we hit him neutrally with Sludge Wave.
capefeather: I hope you got my warning about your PS being too low. In any case, I don't know how important it is to inflict higher recoil on Talonflame if we can tank it and kill it with Thunderbolt anyway. I also feel that we should lose to Chansey, and having 114 HP gives us the opportunity (but not necessarily the incentive) to beat her. The Speed and Sp. Attack are fine, though.
HeaLnDeaL: The Speed is too high and the Sp. Attack too low. Expert Belt isn't really a viable item as is, so I encourage you to try the calculations again with a higher Sp. Attack stat and with no boosting item. Similar to the concerns I have with NumberCruncher's Speed, do you really want to be able to beat Greninja and Starmie? I understand that you want to outspeed Talonflame, but it doesn't really matter if we can tank a hit from it and kill it back with a Thunderbolt. I look forward to your future update, because I'm not sure what I see here yet.
Qwilphish: I disagree that Keldeo is good setup bait, as he threatens us if we've Mega Evolved with Secret Sword, and can land a Scald burn on us as well. I do love the justifications for the Defenses, though, and you explain very well why we should have little to no incentive to run HP Ice on our CAP. The Sp. Attack is not abusively high and it does what we want, so hats off to you for showing some restraint. Also, to make the BST cleaner, I would drop Attack to 64 or raise it to 69.
Psychic Daryl: No… just… no.
Dragonblaze052: I believe you should run some calculations with something other than a Life Orb, as we should have the incentive to run other items as well. Though you haven't justified your Speed, it's clear what you are going for- outspeeding Thundurus. I do need to see some Thundurus calculations, however. The bulk is fine, as it wins against Talonflame and loses against what it should.
Whew! That's a lot of feedback. Will do some more tomorrow.
