Sure
I have used various team methods. A female companion can be very helpful in many ways. They can keep a separate insurance side count, or a side count for a particular side bet you want to beat, or jump in and play an extra hand when the count is positive, or play an extra hand when the count is negative (to eat cards with minimum bets since a single player has to play 2 x minimum on two hands), or to play at the next table so the two of you can share hot shoes, or to get bored and "complain" during a negative shoe to give you a reason to Wong out, or to play at another table across the pit and distract the bosses, etc. Even if she doesn’t know how to count cards she can be a valuable asset to you.
The list goes on and on, and that is only with two people. Imagine how much damage you could do with several players on a team!
