First, this deck need 4 Execute Order 66 which will be put in the deck before I draw my starting hand making my deck a 34 cards deck. This should help against mill and it is a nice removal card.
5 low-cost upgrades which can special chain with Niman Mastery are Inferno Squad ID10 Seeker Droid, Mastermind and Force Jump. Other chaining possibility is with Force Wave. To help do multiple target damage, there is also Fear and Dead Men.
