Why did my Prankster Sableye go last?

Here’s thebattle replay

Edit: But since it’s mega-evolved shouldn’t its ability also change into Pixilate? That is where I’m confused.

I came to the conclusion that there is an issue with Showdown changing abilities when Pokémon Mega Evolve. As you see in your replay and in this onehere, Gardevoir retained the ability Prankster (from Trace) when it should have gotten the ability Pixilate after Mega Evolving.

I was not satisfied with this so I tested my theory using a Chlorophyll Venusaur. Breloom should have outsped Mega Venusaur but the results reinforce my theory as Mega Venusaur retained the ability Chlorophyll for 1 turn after Mega Evolving and thus allowing it to move before Breloom. However, the next turn Mega Venusaur’s ability (presumably) became Thick Fat and lost the Chlorophyll speed boost. View the results for yourselfhere.

Hope this helps.(Props toKawaii Terlorfor helping me test this out)

Because Gardevoir had Trace before it Mega-evolved, and traced Prankster from Sableye. Gardevoir’s almost always faster than Sableye, and since with Prankster it was in the same speed bracket as Sableye, therefore it went first.

In Gen 6 (XY/ORAS), turn order is determined before mega-evolution happens. Because Gardevoir traced your Prankster and almost guaranteed had higher speed, it’s able to use a priority move before Sableye is able to use its move only on the first turn because its turn order was determined while it was a base Gardevoir with traced prankster.
