I can't seem to find much in the rules about the mechanics of "taking control" of another unit. Do damage/focus stay on the unit? How about enhancements? Force cards?

Thanks.

There's some information in the FAQ about taking control of units.

-Damage stays.

-Focus tokens stay.

-Enhancements stay in general. However, the enhancement stays under the control of the original player. If this results in an illegal attachment state (eg the enhancement says "enhance friendly unit" and now it is no longer enhancing a friendly unit) the enhancement is immediately discarded.

-Force cards return to the supply (exception - in 2v2 your partner can take control of your unit and keep the force card).

cool - thanks
