How to anim_fighter Animations?

[u lil nerd]

Hello, I was wondering how to use anim_fighter animations, namely the ones that play when you gain a debuff, say stun for example, you get that yellow flashing outline, I tried using

anim_fighter:Flash(0xff00ffff, 0.1, 0.3, 1)

 in a battle card which I have used before with something else but that was in a character file.  If I wanted to activate this using a battle card, how would I do it?  the event handler PLAY_ANIM doesn't seem to help either

Thanks
