How would a Destiny Bond, Scarfed, Trace Gardevoir do against Excadrill with Sand Rush?
I believe Gardevoir would...hit someone like 800+ speed.
If Excadrill uses the turn to say, sword dance, and then sees you use destiny bond, it's more than likely going to switch, allowing you to send in a pokemon that can kill it before it kills the counter due to it not having the swords dance boost, or you can continue to use Gardevoir and end up killing another pokemon.
And obviously if it attacks and ends up killing you (due to not caring, or because they don't expect/know gardevoir has access to destiny bond) than you take out probably their most potent sweeper.
If that makes sense, tell me what you think.
Also...Focus Sash wouldn't make much sense unless sand rush gives you an immunity to sand. (has that been checked?) because the storm would kill you after that one turn. Not only that, but you NEED the Scarf.
And I don't mention focus blast because we all know how accurate that move is.
