lol hey there tough guy, im not sure you understand, but no one here changed your previous silly team from what it originally was.
First of all, the ONLY reason we talked about Chansey was because you originally had a terrible choice of using Mega Audino [nice meme]. We gave you a BETTER pokemon to fit the SAME role (well, Mech suggested Chansey, who I believe is still terrible outside of any stall archtype). Clefable is currently S rank in OU (s rank being given only to MMetagross, MAltaria, and Clefable) and is the premier tank in OU, with 2 wonderfull abilities (Unaware and Magic Guard) as well as a solid cleric movepool (Wish, Heal Bell, TWave, SR, Toxic, etc) and a great typing in Fairy. To be frank with you, it shows your lackluster ability as a player to pick VAPOREON (a commonly frowned upon mon in OU) as a cleric when you can pick something (Clefable) who pairs VERY WELL with your current core. I'm purposely being aggresive towards you because you directed your response towards Mech and I in the same manner.
SD Mega Scizor with U-Turn is a fairly new set, and I wouldnt be surprised if you still had the "Gen 5 Mentality" where all moves that force you to switch (bar baton pass) are automatically bad with a set up move. I dont think you understand the logic behind my suggestion. SD Mega Scizor purposely plays as a defensive pivot early - mid game (very much like Rotom-W) in a sense that it walls the threatening majority of OU (Weavile, Metagross, Altaria [except Special, which is a bad set], Clefable [Fire coverage is outclassed by TWave and Encore], Mega Alakazam [easily can force switches; bad if any hazards are up], Gengar [gets free kills if scizor or Manec arent inside spamming Bullet Punch], Landorus [Scarf Lando currently DESTROYS you mid game], etc), as MScizor is quite bulky. It also has a nice Steel Priority if you need it to revenge kill something that could blow a hole in your team (Kyurem B comes to mind). THEN, once your opponent's team has been SUCCESSFULLY weakened, you set up an SD and clean their team up with Bullet Punch. I'll even leave a replay for you since I've seen this happen and KNOW this is effective. Same can be said for CM Volt Switch Raikou, though it's purpose is different than that of Scizor's. I wont deny that Manectric isnt an ok choice, but Scizor fits your team archetype (Balance) much better than Manectric does.
As for the IV stuff on Infernape, i KNOW it's meant to be frail. I saw Endeavor. I've USED the set. Yes, IVs are needed. Lead Matchups are a thing, and in ORAS, there are Suicide leads (Azelf, Infernape, Terrakion), General Leads (Tornadus-T, Hippowdon, Bulky Chomp [all these leads are usually picked due to team matchup), and Passive leads (Ferrothorn, Skarmory, etc). Mons in the first two categories will often times be the ones you use Endeavor on, as the power creep in ORAS is quite noticeable, so 31 points wont make a difference in this tier. Whereas against passive leads, you can aim to keep you Infernape healthy enough to come back late game (Fake Out and Mach Punch). Like, I'm not blind or stupid lol there often times WILL be specific situations like that (Infernape is your only way of dealing with TTar and/or Excadrill in sand).
As for the next point, U-Turn GAINS momentum. Pursuit LOSES momentum in EXCHANGE for removing a threat. Gengar used to clean 6-0 your old unedited team. Like, we know what U-Turn and Pursuit do lol, dont try to say the do otherwise. U-Turn and Pursuit are completely different moves which perform different roles.
Also, if you want a real rate, here goes:
Use Clefable because Vaporeon is utter garbage in OU and quite easily 2hko's by common metagame threats, while not doing much in return, whereas Clefable can either Encore them (into a recovery or set up move; walls and sweepers alike), Twave them (speedy mons), or even run Heal Bell on the Cm set since you're so fond of Clerics in a tier where they arent that great/necessary.
Next, you need a Ground type because you're a sitting duck for VoltTurn strategies. I suggest the Bulky Chomp set over infernape, because admittedly, Infernape is subpar in OU and highly outclassed. So bad it's not funny.
Use the Scizor set i suggested or dont use Scizor without Pursuit. Aerial Ace wont be an option when Keldeo completely stomps on you with Scald (chance to burn) and Hydro Pump anyways. Like seriously, Bisharp would be a better fit that your current Scizor. (Clefable walls Keldeo anyways lol)
Change Manectric for Tornadus-T, a current great mon in the metagame. Or if you're stubborn and wish to keep Regular Scizor, Mega Aerodactyl works here as well. Use Assault Vest for Torn-T, and Roost + 3 Attack for aero.
Give Ferrothorn a better spread of 252 / 100 / 156 Sassy Nature and Leftovers to better help check Kyurem B. Spikes are pretty mediocre in a defog infested metagame (especially since you're not abusing bisharp for this team), but the can work.
Use the smogon Standard spread for Tank Slowking in OU.
Im generally an ok person on the RMT section (behavior wise) and like to help people who have a small grasp or greater of the metagame for tiers like OU and UU. Investigate how viable a suggestion is before mindlessly shooting them down.
