For each (Integer A) from 1 to 10, do (Actions)
Loop - Actions
Set scaler = (100.00 + ((Real((Integer A))) x 5.00))
Animation - Change (Summoned unit)'s size to (scaler%, scaler%, scaler%) of its original size
-------- this wait, even though it says 0.01, can't get any smaller than 0.27 --------
Wait 0.01 seconds

this will increase the summoned unit's size by 5% every 0.27 secs. it will look jerky, but the only way to aviod that is to do it in JASS. look for Daelin's tute on beginner JASS. then i think the relavant stuff is in his advanced one about smooth knockback.
