After you have used Trix of the trade on a player you can deal damage with bombs such as saronite bomb and frag belt (have not tried other bombs) without triggering the 6 seconds buff and it will have the same effect as if you would have pulled with a ranged attack like throw and shoot, this means you can pull a group of mobs and still have the buff left to transfer threat for 6 sec when you start attacking for real.
Misdirect report addons will not announce if you pull like this.
