I do it duo with my level 74 myth friend, Alric. ALL the time.
Our method.
First round, -Friend uses Pierce -I use Trained feint on Taurus
Second round -Friend uses Fire dispel on Taurus -I use Amulet feint on Taurus
Third round -I use feint tc on Taurus -Friend uses Myth dispel on Ervin
Fourth round -I flee -Friend uses Fire dispel on Taurus
Fifth round -I use trained feint on Ervin -friend uses Myth dispel on Ervin
Sixth round -Friend myth dispels Ervin -I use Amulet feint on Ervin
Seventh round -I use tc feint on Ervin -friend uses Fire dispel on Taurus
Eighth round -I use sharpened spirit blade on Friend (my pet gives me the card) -friend uses normal spirit blade on him self
Ninth round -I use TC spirit blad -friend uses Humongofrog (After we get the convert on Taurus)

Basically we use the three feint, three blade rule.
One of us has to stay consecutive with the dispeling. It just takes a bit of strategy I guess. It's even better with a storm, because the storm is always guaranteed a one shot kill (assuming they have Full waterworks gear)
After doing this Tower over 10 times, I have gotten my Lexicon blade athame, and my Aureate Band. I basically know this tower better than the back of my hand. If anyone is every having difficulty with this tower. Read a guide on Wizard101 central.
