As the poster above said, for trading.

When you ace an AW or FAW, you get an increased chance of getting an SR from her chest (around 1% increase). You get ace by dealing the most actual damage to the witch (damage after the witch hits 0 health doesn't count). Normally I try to stop at just over half for FAW that I've found then send the FAW off to my alliance and 5 of my regular senders, though for a few of those videos I did more damage than I normally do to show the deck.
