So, if you have zVeers Imperial Troopers + Piett, you can get infinite TM.
While you're infinitely gaining TM and your Imps are taking turn after turn, just use Piett's Inevitable Failure on his turn ... every single time. IF marks a Piett ally and for whatever reason inflicting Marked on yourself still counts for the feat (I know, I inflicted 19 marks on the NS during a battle using JKR, then while I was waiting for JKR's stamina to go back up, I used Imps for something else and it completed the feat for me.)
Combined with the AoE dazes, zVeers Imps + Piett shouldn't have any trouble at all marking up a storm, and for my money it seems like you get more of them in 4 minutes than you can with JKR because with JKR you have to wait for GMY to take 43 turns before JKR's turn comes up again, but with Piett each of the Imps pretty much acts only once in the sequence (speed doesn't matter much once the TM train is running).
Finish Ventress & daka off to prevent their TM jumping of course, but don't worry about anything else. The NS gain health & prot on any death (including every time you kill the zombie), but The Emperor's Trap stacks up offense even faster ... if Ventress & daka are gone (when they TM jump and take a turn, it resets TET).
It's also might be useful to know that I got credit for killing 101 enemies in that 4 minute 30 second battle. It's a good way to rack up kills for Sector feats & Event feats.
