Special entity targeter

Hi there!

i am trying to achieve something very cool, and i want to make a mob at spawn tag another mob near spawn,
but i got one problem;

Mythicmobs only has a targeter for all EntitysInRadius, not for the closest entity,

i looked at the wiki, and it says that vanilla targeters works too (or i understand it that way)
i tryed @e[c=1] but it dint give any result...

any way to get this running?

thanks
