Part 1. You ain't done with writing yet! >:3
I included the Speed nature but I realized that it isn't necessary. Also, I'm not talking about Blaziken. I'm talking about Mega Blaziken. Blaziken is like he always have been, a shitty starter pokemon. But Mega Blaziken is sick.
1: Why wouldn't he switch out Blaziken if you send out Darkrai at the same time he sends out Blaziken? Darkrai obviously got more Speed so that's retarded from his side.
2: Blaziken got 259 Speed with IVs, EVs and without nature. Mega Blaziken have 299 Speed with IVs, EVs and without nature.
3: Event Blaziken which allows you to get Mega Blaziken got the hidden ability Speed Boost which passively increases his Speed stat by 50% after every turn. Also, why the hell would you go with his Blaze ability anyways?
4: The first turn when you evolve Blaziken to Mega Blaziken will give you a 50% Speed increase at the end of the turn. And with Mega Blaziken's 299 Speed that would end up with him having a total of 448,5 Speed (result of my calculator).
5: If you send out your Darkrai the turn after you see him switch into Blaziken he would already have evolved to Mega Blaziken, used a Swords Dance and have 448,5 Speed stat. Your Darkrai would be entirely useless in that situation. So your only bet with Darkrai is if you switch into Darkrai at the same time as he switches into Blaziken, but that would only force him to switch pokemon again since he won't sacrifice his Mega Blaziken for no reason at all. That would just be foolish for him to do.
Sorry for the numbers, but it just felt easier to explain stuff if I write it this way.
Also, am I the only one who can see that your background is pretty screwed? It's hard to see where to click when it is like that
