The writeup on Allakhazam is solid, and we use a strat similar to Borneal.
Since adds are %HP based, slow and steady control is the key. Having a dedicated click team (ideally in vent) is also essential. Adds can be controlled by kiting (light, nature), stun (shadow), or mez (magic). Just beware of the blind from the light adds, although after the nerf it's not so bad.
You can decide whether you want to pet tank Fumerak or not...it works.
