Dark Ascension + Mind Bender macro

Hi, I’m tried to create a simple macro which casts both Dark Ascension and Mind Bender for pvp, both are on a 1 min cd and both are instant casts (in pvp). Why is it not working? It casts the first one but will not cast the second even if I press it again.

#showtooltip
/Cast Dark Ascension
/Cast Mindbender

Because they’re both on the GCD.

Best you can do if you want them on the same button is:

#showtooltip
/castsequence Dark Ascension, Mindbender
