All valid points. But you don't have to run Sharp or Slash. they're very good at their jobs granted, but they have counters (even if Aegi beats most of his) and checks. If you run them, you run the risk of being hard countered by a team who's adapted to the most common Pokemon in the tier (which is hard countered to a team that's adapted to that particular team archtype ETC.) Of course that's me being paranoid and Anti-Meta
Thats exactly my point, you have to run them otherwise Deoxys is just wasting its time. Stacking Spikes is worthless if you cant protect them somehow and Spikes are the main reason to use Deoxys, if its just for SR you could use Garchomp or any other offensive SR setter. Deoxys doesnt need any support to do its job (setting up hazards) but it needs support to give that job any value i.e keep those hazards on the field.
If enough support is presented about changing their ranks i am sure that Gary will change his stance, so don't worry about this.
Doubt it but fine. Imo Espeon and Scolipede are very similar cases to Deoxys-D. They work exeptionally well on one specific archetype providing invaluable support for their team without giving free turns. They dont even need support to do their job, Scolipede doesnt need support to accumulate speed and def boosts and pass them to another team member and Espeon doesnt need support to block phazing and stuff, though it needs support to attempt a sweep. Because of that they would deserve a similar rank, meaning somewhere in the A ranks for Espeon and A+ or even S Rank for Scolipede depending on how influential it is on the meta. I am not running into BP that much so I would put it into A+ but thats just me.
The rest of the BP stables can stay where they are imo as they arent that important for the team as the other 2.
Sylveon and Vaporeon are basicly just some kind of redundance and Mr. Mime and Smeargle arent that important for the team to work and all 4 of them could be replaced by other mons.
Well, when I say "cleric," I'm generally talking about Heal Bell. Whether it has Wish or not is another story.
Your right, I messed up the definitions because usually Wish and Heal Bell are found on the same mon.
The thing is, that's kinda debatable. Keep in mind that Sylveon has less physical bulk than Clefable does, and while it's special bulk is better, it's not like it has a field day with most special attackers like Chansey does. Assuming a physically defensive spread, it's in danger of a 2HKO from LO Latios's Psyshock after Stealth Rock, guaranteed with a little prior damage. You beat Latias, though. Aegislash smashes with Iron Head or Flash Cannon while Sylveon does little back. Charizard Y still 2HKOs with Fire Blast. You can beat Thundurus, but if it has Nasty Plot, it sets up and 2HKOs while you do 65% max in return. Unaware Clefable doesn't have that problem. Heatran is Heatran. Keldeo's LO Hydro Pump has a shot at 2HKOing, guaranteed with Stealth Rock or Specs > LO. You can beat Greninja from full health, but like Latios, you still take a ton of damage and have a small shot at being 2HKOed even after Stealth Rock. 0 SpA Mega Venusaur's Sludge Bomb is a 2HKO after Stealth Rock, and even without, it can just spam Sludge Bomb until you get poisoned and then 2HKO that way. You do beat LO Deoxys-S. Landorus's Earth Power has a small chance to 2HKO with no prior damage, nearly guaranteed with a Modest nature or Stealth Rock. Sludge Wave variants outright win if you switch directly into an Earth Power or Psychic or something. Gengar's Sludge Bomb 2HKOs, and LO variants have a shot at OHKOing after Stealth Rock. Mega Gardevoir's Hyper Voice is a nearly guaranteed 2HKO after Stealth Rock. You beat Mega Manectric pretty handily. Mega Alakazam also has a decent chance to 2HKO with Psyshock after Stealth Rock. Survivable, but too close for comfort. Manaphy 2HKOs with Surf at +3, while Unaware Clefable can actually stop it. Volcarona just sets up all over you.
Thats exactly the reason why I wouldnt run a physical defensive spread on Sylveon. Its special bulk is good, but not good enough to leave it uninvested and expect it to take special hits like a champ. On the other hand, even with full investment its physical bulk is still sub par, hardly avoiding the 2hko from most physical attackers even with protect to get lefti recovery.
With a mixed or even pure special defensive spread however Sylveon can take every special attack you throw at it, including Charizards Fireblast and Specs Keldeos Hydro Pump. And pretty much everything weaker means you get a free wish. Especially Keldeo is Wish bait for Sylveon as it cant realy touch it and cant stay in on it at all. Clef on the other hand has a little more physical bulk but not that much more that it would matter and even fully specially defensive it cant take the hard hitters of the tier. Unaware on a Cleric/Wishpasser is imo a somewhat stupid idea tbh as it should be the job of such a pokemon to support its team with Heal Bell/Wishes and not to wall of boosting sweepers, not to mention that Clefable cant wall most of the common boosting sweepers of the tier even with Unaware. Pinsir, Zard X, Tyranitar all walk over it so does everything with a Life Orb or Choice Band.
Besides that, Sylveon's other advantage is more damage, but it's not like it's wallbreaking any time soon. Clefable can also solve its issues with special power and bulk with CM + Bell, which is obviously a legitimate set, but that's probably irrelevant since I think you're referring more to WishTect + Bell.
Its not supposed to wallbreak. But it can do severe damage to everything that doesnt resist it, even threatening to ohko several things that it hits for SE. And yes CM + Bell would be a good set for Clef. As stated before if its only about Heal Bell, Clefable is on a similar level, the wish passing is the problem imo.
