Ok so i would like to bring back up Sylveon because ive finally got time to write a detailed post on the subject.
Sylveon to B or B+
In the case of Sylveon the main sets people are used to are the Specs Set, CM/Baton Pass and the cleric set.Whilst im fairly inexperienced with the latter 2 sets i have been using the Specs set for quite a while now so i will focus on that.
Choice Specs Sylveon
244HP / 252spA / 12 Speed
(The 12 speed IV's are to outrun non invested Tyranitar)
Modest Nature
Item:Choice Specs
Firstly for those who run Shadow Ball, can you give me a reason why to run it as i honestly dont see a point in using it over Baton Pass. Anything its super effective against Hyper Voice hits harder with the exceptions being Doublade and Gengar, The former is also 2hkoed by HP Fire/Ground and the latter being hit harder by Psyshock anyways. Baton Pass gives you the utility to predict switches and gives you the switch advantage due to speed tier against popular pokemon like Landorus-T and Manectric when they Volt Switch/U-Turn on you or of course if you predict that they will switch into Heatran or Ferrothorn you can bring in your counter after they have swapped.
The Specs Set is one of if not the best Special Wallbreaker set in the current meta due to Hyper Voice, Sylveons base 117 STAB move thanks to her ability pixilate that also goes through Substitute. Whilst most will argue that this set is outclassed by Mega Garde as Garde is faster, has a larger movepool and is not forced into a single move, Sylveon does hold some advantages over Mega Gardevoir.The most important thing to note is that of course it does not take up a mega slot. Sylveon also is able to hit a fair bit harder with Hyper Voice and due to its fairly good base Defensive stats (95/65/130) is able to function very effectively as either a primary or secondary special tank without any Special defence investment. This allows it to take both Special and Physical hits much better than Gardevoir (Mega) ever could whilst dishing out higher damage with Hyper Voice.
(2 quick examples)
- 252+ SpA Choice Specs Pixilate Sylveon Hyper Voice vs. +1 252 HP / 0 SpD Mega Sableye: 332-392 (109.2 - 128.9%) -- guaranteed OHKO
- 252 SpA Pixilate Mega Gardevoir Hyper Voice vs. +1 252 HP / 0 SpD Mega Sableye: 270-320 (88.8 - 105.2%) -- 31.3% chance to OHKO
- 252+ SpA Choice Specs Sylveon Hidden Power Fire vs. 252 HP / 168 SpD Ferrothorn: 292-348 (82.9 - 98.8%) -- 31.3% chance to OHKO after Stealth Rock
- 252 SpA Mega Gardevoir Focus Blast vs. 252 HP / 168 SpD Ferrothorn: 238-282 (67.6 - 80.1%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
In the case of Ferrothorn having the lower speed tier is much more beneficial as it allows Sylveon to either OHKO or 2HKO it with HP fire whilst Ferrothorn would OHKO Gardevoir with Gyro Ball
- 0 Atk Ferrothorn Gyro Ball (99 BP) vs. 244 HP / 0 Def Sylveon: 288-342 (73.4 - 87.2%) -- guaranteed 2HKO after Stealth Rock
- 0 Atk Ferrothorn Gyro Ball (150 BP) vs. 0 HP / 24 Def Mega Gardevoir: 422-498 (152.3 - 179.7%) -- guaranteed OHKO
Sylveon is also able to beat majority of the pokemon in the higher tier however a fair few come down to 50/50 matchups.
(Note the matchups ive listed are assuming both pokemon are on 100% hp and no crits).
S rank
Sableye (Mega) (Sylveon wins)
Keldeo (Sylveon OHKOs all sets. Keldeo can 2HKO with Specs Hydro Pump if Sylveon Switches in)
Metagross (Mega) (Metagross Wins)
A+ rank
Altaria (Mega)- (Sylveon beats all sets except D Dance if Altaria has a boost before Sylveon switches in)
Azumarill- (This matchup is a perfect example of a 50/50 matchup as whoever hits first wins this no matter what set is run Azumarill runs. if Azumarill has invested 98 or more EVs into Speed it wins. Neither can switch safely into the other)
Bisharp- (Bisharp wins unless it switches into a Hyper Voice or trys for a Sword Dance. Both these Pokemon OHKO each other.)
Charizard (X)- (Charizard OHKOes with Flare Blitz however is OHKOed if it switches in after Mega Evolving or Switching in pre Mega with Rocks up or 40% prior damage.)
Clefable- (Sylveon wins. Clefable is 2HKOed with 1 or less calm mind boost and can at best 3HKO Sylveon with a +1 boost).
Diancie (Mega)- (Sylveon wins OHKO with Hyper Voice compared to Diancies 2HKO with Diamond Storm)
Gengar- (50/50. Sylveon OHKOs with Psyshock or 2HKOes with Hyper Voice if Gengar Switchs in. Life Orb Gengar has a 65% chance of OHKOing with Sludge Wave if rocks are up.)
Gliscor- (Sylveon wins. OHKOes the physical defensive set or 2HKOes the Special Defensive set.)
Gyrados (Mega)- (Sylveon OHKOes with Hyper Voice and is 2HKOed by Waterfall. Gyrados wins with a Waterfall flinch or can OHKO with rocks up if it has already pulled off a Dragon Dance).
Heatran- (Heatran walls Sylveon completely unless Sylveon is running Hidden Power Ground which 2HKOes Heatran or OHKOes offensive heatran if not running Air Balloon).
Landorus-I- (Sylveon generally wins. OHKOes with Hyper Voice and is 2HKOed by Sludge Wave)
Landorus-T- (Sylveon OHKOes the Scarf Set and in return is 2HKOed by Earthquake. Sylveon also OHKOes the physical defensive set with rocks up. If the U-Turn is expected into something that can take a hit from Sylveon use Baton Pass instead to keep momentum)
Lopunny- (Lopunny has around a 50% chance of OHKOing with Fake Out +Return and is OHKOed back with Hyper Voice.)
Latios-(Sylveon wins. OHKOes with Hyper Voice and is 2HKOed by Psyshock).
Slowbro (Mega)- (Sylveon wins. 87.5% chance of OHKOing with Rocks up or a 2HKO if it boosts).
TalonFlame- (Talonflame offensive sets win with either a OHKO with choice band and rocks up or 2HKO without).
Thundurus- (Sylveon wins. OHKOes with Hyper Voice and Thundurus 3HKOes with thunderbolt)
Sylveon does have some flaws however. It is walled completely by Chansey and Blissey and Depending on which HP it is running Ferrothorn, Special Defensive Mega Scizor and Heatran can wall it very effectively. It is also locked in to a single move which makes it fairly easy to take advantage of however Hyper Voice is by no means a bad move to be locked into allowing Sylveon to 2HKO most pokemon that resist it or you can even use baton pass to keep momentum if you suspect they will switch to something that walls your set.
All in all i feel Sylveon is a very solid pick in the current metagame and would not be out of place in B+ or the A- Rank.
