Mega Gardevoir has a pretty unique standing in this Metagame as an expanding force abuser and the second strongest one behind Hoopa-Unbound. However, unlike Hoopa-Unbound, Mega Gardevoir has multiple unique traits to aid in its Expanding Force spam.
1. Most obvious difference is that Mega Gardevoir is part Fairy, and thus can threaten most of the Dark types that otherwise would be immune to Expanding Force with its Fairy STAB. Not only that, but Mega Gardevoir is much better off defensively with Psychic/Fairy having resistances and lacking nasty weaknesses to Bug (U-turn) and Fairy itself. Hoopa-U actually has better raw bulk, but in practice is frailer because of its lack of resistances. You’re much sturdier against Pokemon like Keldeo, Mega Garchomp Z, Latios, most Magearna, and Mega Golisopod
2. The other most obvious advantage Mega Gardevoir has is its Spe stat. With 100 Spe, you outspeed Annihilape, Excadrill, Ceruledge, Overqwil, Gholdengo, Baxcalibur, Glimmora, Rotoms, Gyarados, and speed tie all the base 100 Pokemon.
100 is also the Speed that lets you outspeed Mega Zeraora if Sticky Webs are up, even with Modest, and still outspeed timid Rotom-Wash. Only do that if you want to use Sticky Webs.
Hoopa with Choice Scarf or Webs otherwise is barely too slow to outspeed the Z megas and can’t even outspeed Mega Sceptile (speed ties with Webs funny enough) either.
3. Mega Gardevoir also has access to Mystical Fire. It provides Gardevoir with a more reliable means to beat Steel types, especially Scizor, Mega Golisopod, and Magearna. You hit most Steel types super effectively and also lower the SpA of any Pokemon you hit. So if you’re fighting Magearna, you can lower its SpA, weakening Stored Power, while dealing solid damage too.
Gholdengo faints to STAB Dark Pulse from Hoopa, Mega Gardevoir outspeeds non-scarf variants and avoids taking damage from Make It Rain. Even Scarf Variants wouldn’t KO after the SpA drop.
Against Mega Heatran, you lower its SpA which lets you tank more hits. You can also potentially exploit regular Heatran with Flash Fire by copying it with Trace as pre-Mega Gardevoir, which then boosts your own Mystical Fire if they Magma Storm you, and prevents you from being trapped. Regular Heatran is tough, but managable for Mega Gardevoir since Expanding Force can 2HKO even SpD Heatran at +1
+1 252 SpA Gardevoir-Mega Expanding Force (120 BP) vs. 252 HP / 252+ SpD Heatran in Psychic Terrain: 157-186 (40.6 - 48.1%) -- guaranteed 2HKO after Stealth Rock, 1 layer of Spikes, and Leftovers recovery
+1 252+ SpA Gardevoir-Mega Expanding Force (120 BP) vs. 252 HP / 252+ SpD Heatran in Psychic Terrain: 173-204 (44.8 - 52.8%) -- 85.2% chance to 2HKO after Stealth Rock and Leftovers recovery
Hoodra can’t much fight back if its SpA is constantly being lowered and can’t Dragon Tail Mega Gardevoir out.
Mega Gardevoir 2HKOs even bulky variants of Excadrill with Mystical Fire, and doesn’t have to worry about Focus Miss.
There are more examples of Mystical Fire being useful. It’s a relief mostly for when you don’t want to rely on Focus Miss hitting. And even so, you can give Gardevoir Aura Sphere as well for Fighting coverage. It improves the Heatran match-up and Expanding Force is so strong you can 2HKO Gholdengo with just that.
252 SpA Gardevoir-Mega Expanding Force (120 BP) vs. 0 HP / 4 SpD Gholdengo in Psychic Terrain: 164-193 (52 - 61.2%) -- guaranteed 2HKO after Stealth Rock
With Psychic Terrain support from Indeedee, Mega Gardevoir is a pretty powerful Mega. With this limited metagame, not much is able to reliable switch into Mega Gardevoir’s extremely powerful Expanding force, and has the best complimentary STAB for Psychic spam.
