You say that yet altruis +twin slice, eye beam, chaos nova, and immolation aura are already wild tier anti aggro tools. Skull of guldan is easily wild tier. It definitely has what it takes to play vs the aggro wild decks.
As long as its aggressive enough to kill mage quest and combo warlock (with help from card like loatheb) you might see demon hunter take a nice spot in wild. Most wild decks are not all over the place, taking card from all over hearthstone; they are condensed from one selection group and pull a couple cards here and there.
