Possessing a possessed TAG

Of course. There is nothing preventing you from hacking a TAG, even in Possessed state.

 

The problem is that "being possessed back" (or something similar) is no cancelation clause for the initial possession.

 

Wouldn't the second Possession override a number of effects from the initial possession? Essentially you would get your TAG back to use but using the Possessed Profile. Though it would count as a casualty and not generate an order etc?

 

Yes, that's the correct answer. Your re-possessed TAG will still have the possessed status and profile.

 

And considering Exorcism is an attack, you can't un-hack it with a (Defensive) Hacking Device if you possessed a possessed TAG

 

I think regular hacking devices have Exorcism too.

 

you can still flip a command token however

 

Hence the paranthesis. Evo and white does, too.

Yes indeed. Always keep one in reserve!

 

Yo dawg, I put some Possession on yo' Possession...
