How Many Powers Can Be Used in 1 Turn?

You guys are good at theoretical nonsense turns, right?

I’m trying to figure out the maximum number of powers that can be used in one turn.  I’m thinking that our team needs to have Xtreme Argent, and Dark Watch Expatriette (see below).  I’ll also include Grandpa Legacy, Doctor Medico, and The Wraith.

Now, this is just my first thought, but:

Argent uses Lyra, to use Harp, to use his base power.  He passes it to Medico, who is fully set up.  Medico grants two powers to Wraith with Doctor’s Orders (1 from the card, and 1 from not healing 2+1 with Second Opinion).  Then, Medico uses Pulse, to give everyone another power.  Legacy gives one to Argent, who has now used 5 (his base and 4 instruments).  This gives Medico another play- which he uses for another Doctor’s Orders on Wraith. Expatriette aims.  Wraith does Wraith stuff.  Great!  Now, on the back end, Expatriette Unloads. Argent decides not to heal, and uses another power, to Scherzo on Medico, who saves himself with On the Brink, giving everyone one last power, for 21 total.

Any better ideas?
