Typically, you put the Geonosians in with 88 lead and they dot on critical hit making spy go every second turn and sometimes twice in a row even though his base speed is really low.
I've been bringing up this team: 88(L G9), GS (g11) , spy (g8) , sf (g11) and Vader (g10) /Boba (g9) some only Lvl 80. Orrrrr it might be Zadar, sf (to make tmg for spy), spy, Boba and ep.
From reading some posts, I agree it won't be fast enough for heroic tank. I have read though that spy is the anti-Chaze toon, which is cool.
Suggestions welcome.
