If M-Sableye leaves the tier, We'll probably get to see more usage out of Mega Gallade with one of his most reliable counters gone. Should be fun to use him on a serious team again should that be the case.
Gallade-Mega @ Galladite
Ability: Justified
EVs: 4 HP/ 252 ATK/ 252 SPE
Adamant Nature
- Shadow Sneak
- Drain Punch
- Zen Headbutt
- Swords Dance
Typical sustain set, set up swords dance when you get the chance and +2 Drain Punch will be healing almost any damage that isn't OHKO'ing you, but what most people underrate is the power of a boosted Shadow Sneak, especially against the competition he's speed-tying against in Gengar and Lati@s, with a boosted Shadow Sneak able to dispatch them without having to gamble on the speed game.
+2 252+ Atk Mega Gallade Shadow Sneak vs. 4 HP / 0 Def Latios: 276-326 (92 - 108.6%) -- 50% chance to OHKO
+2 252+ Atk Mega Gallade Shadow Sneak vs. 0 HP / 0 Def Gengar: 346-408 (133.5 - 157.5%) -- guaranteed OHKO
also post note, boosted shadow sneak also dispatches M-Gardevoir, which would normally wall the hell out of Gallade.
+2 252+ Atk Mega Gallade Shadow Sneak vs. 16 HP / 0 Def Mega Gardevoir: 326-384 (116 - 136.6%) -- guaranteed OHKO
