What action will i use?

Move unit (instantly) to (position of target unit of ability being cast)?

That will move the unit instantly... That is like blink...

Uh...

So what are you trying to ask us to do for you? That essentially would move a unit to what the triggering ability is targetting. So its blink without the graphics.

call SetUnitPosition(GetSpellAbilityUnit(),GetUnitX(GetSpellTargetUnit()),GetUnitY(GetSpellTargetUnit()))

that will move the caster of the spell to the target unit of the spell.
Is that what you want.
