Could we refer to my post on the previous page for a discussion on Mega Gardevoir on why it should be either B+ or A rank.
Mega Gardevoir
I'd like to nominate MGard for B+/A, as it is one of the most outstanding Fairy types out there. It walls most of the dragon types, and can take many special hits.
- Gardevoirite
- Pixelate
- 4HP/252SPA/252SPD
- Hyper Voice (x1.3 Pix x1.5 STAB)
- Psychic
- Calm Mind/Shadow Ball
- Thunderbolt/Energy Ball
Great coverage moves and a ton of power. The two biggest dangers I've seen are Gengar and Aeiglash. Gengar it can take a hit from and Psychic down, and Aeiglash is S Rank and you will need a counter for. Also remember that its only weaknesses are Poison, Steel, and Ghost, with the ghost enemies covered prior, Steel Enemies are definitely a weakness, but Poison being mostly special Gardevoir can take a hit or just deal out a psychic with its 100 speed.
>it walls most dragon types
Using Garchomp and Dragonite, pretty much the only relevant OU dragons:
252 Atk Garchomp Earthquake vs. 0 HP / 0 Def Mega Gardevoir: 232-274 (83.7 - 98.9%)
252 Atk Garchomp Earthquake vs. 252 HP / 0 Def Mega Gardevoir: 232-274 (68.2 - 80.5%)
252 Atk Garchomp Earthquake vs. 252 HP / 252+ Def Mega Gardevoir: 154-183 (45.2 - 53.8%)
So, no.
252+ Atk Dragonite Earthquake vs. 0 HP / 0 Def Mega Gardevoir: 174-205 (62.8 - 74%)
252+ Atk Dragonite Extreme Speed vs. 0 HP / 0 Def Mega Gardevoir: 140-165 (50.5 - 59.5%)
etc.
Gardevoir's only form of recovery is also wish, which is not reliable. It just doesn't have any walling capabilities (but does counter Lati@s) but has just enough bulk to check (except if they, you know, have boosts.) However, Scarfed Gardevoir is also capable of this, and that does not take up a mega slot AND can use Trick+Scarf, potentially crippling something like Blissey, or troll something with Destiny Bond.
Anyway, looking at Mega Gardevoir:
Pluses:
-great 165 special attack
-good special bulk
-Calm Mind
-powerful attack in Pixilate Hyper Voice which can bypass substitute
-good coverage in Ghost/Fairy/Psychic/Fighting
-okay speed
Minuses:
-only okay speed. 100 is really not good for a sweeper. And, unlike Medicham (who also has 100 speed), Gardevoir can't boast ridiculously powerful attacks without boosting with Calm Mind, limiting its capability to break walls. It can, however, 2HKO nearly everything with various coverage moves: Mega Venusaur is 2HKOed by either of Psychic or Psyshock, Heatran is 2HKOed by Focus Blast, and anything that doesn't resist Pixilate Hyper Voice is either OHKOed or 2HKOed by it.
-weakness to steel a ghost. Psychic typing is an unfortunate liability right now, with Ghost being a very popular attacking type. A Steel weakness is primarily bad because of Bullet Punch, as scizor is still a very common Pokemon
-poor physical bulk. It's bad, nuff said
There is also, however, Gardevoir's tremendous support movepool, which in gen V NU made it a highly popular choice, as it kept the opponent guessing as to what its role in the team would be. Of course, you'd not want to waste your mega on a Dual Screener, but Gardevoir can run something like Will-o-Wisp to take care of its counters: bring Gardevoir in on something that doesn't threaten it, and use WoW as the opponent switches to Scizor or Excadrill or something. Then you can just switch out, with your counter crippled for the rest of the match (sans heal bell.) But, adding in support moves, it gets a bit crowded. Will-o-Wisp is about all it can afford to run alongside three attacks, or CM+two attacks.
All said, M-Gardevoir can hit hard, can do a bit of team support by burning physical attackers, and can boost to break through walls (or Psyshock) and has the coverage to wreck defensive cores, but has very poor physical bulk, only decent speed and is vulnerable to common threats like Scizor and Aegislash, so I would put it at B judging by what else is in there (lolM-Alakazam.)
