No, it's the right one. I just ran it myself.

Now for my entry:

Mega Gardevoir is a notorious stall killer, and Mega Sableye doesn't do anything to change that. Gard OHKOs Mega Sableye if Sableye doesn't use Calm Mind on the switch, and takes little from an unboosted Shadow Ball. Even if Gard switches in on Calm Mind, it still has a good chance to OHKO when Mega Eye is at +1. +1 Shadow Ball still doesn't come close to an OHKO either. Gard actually still wins if +1 Shadow Ball crits, and Hyper Voice misses the KO. Running Modest over Timid is also an option for a better chance to OHKO +1 Mega Eye.
232 SpA Pixilate Mega Gardevoir Hyper Voice vs. 252 HP / 4 SpD Sableye: 402-474 (132.2 - 155.9%) -- guaranteed OHKO
232 SpA Pixilate Mega Gardevoir Hyper Voice vs. +1 252 HP / 4 SpD Sableye: 270-318 (88.8 - 104.6%) -- 25% chance to OHKO
0 SpA Sableye Shadow Ball vs. 0 HP / 0 SpD Mega Gardevoir: 96-114 (34.6 - 41.1%) -- guaranteed 3HKO
+1 0 SpA Sableye Shadow Ball vs. 0 HP / 0 SpD Mega Gardevoir: 140-168 (50.5 - 60.6%) -- guaranteed 2HKO
Worse case without hax, Gard comes out with 40% health left. Any other case leaves it much healthier.
