PvP Trinket w/ Gnome Racial Smart Macro

[Bílly2012]

I'm trying to design a macro that will try to cast the gnome racial on use. If it succeeds it will /stopmacro, but if it fails then it will go onto the next part. Something like:

/cast Escape Artist
If cast=true or GCD=true or something !<--- Here down.. uncertain how to write this macro
Then /stopmacro
If cast=false or GCD=false or something
Then /use 13

The issue is, I'm not sure how to write this out correctly. But you get the idea right? Do I need to go into a /script? Any thoughts?

What you're wanting done can't be done. Macros cannot check for cooldowns and all of that advanced stuff. Addons and macros used to be able to automate stuff depending on buffs, etc. but automation was removed during vanilla wow. You're either going to have to make 2 different keybinds or 1 macro with a modifier to cast both of them.
