Hey, I wanna give you props for giving Reshiram-Amy's Lapras Perish Song in doubles (not sure if in Zekrom too).

It fits her butthurt character so much, like "even if I don't win, you won't either" and she goes almost always for it!  And then spams protect to ensure it goes through!

And it makes the peak of the battle even more interesting because suddenly apart from just a strong ace you have to deal with a hard time limit too!
