Now I think of it... I've done this a few times.... and it was bloody... did it with two systems
UWZ: I did place a few card on the table- all snipers. the rest were Cartel cops.... and it was harsh. Taught lessons about protecting flanks in that one.
40k: Pre-5th Ed, I fielded a Deathwing force with everyone Deep Strike, a Ravenguard force with one lone unit of scout snipers and a Drop Trooper list before they changed the codex (again). Dangerous to play and very very messy in all the games.... Even the losses were fun though most folks have no idea how to face deepstrike- at least back then.
Players have mostly figuredit out now... but with the new outflanking rule, it give me many options to mess with folks.
