Here is my take on the best reserves team:

--Raxus Prime--
55 Kazdan Paratus
35 Zuckuss, Bounty Hunter
20 K-3PO
20 Yoda, Force Spirit
19 Monnok
17 Ghhhk
15 Lobot, Computer Liaison Officer
12 Gha Nachkt
3 Ugnaught Demolitionist

You have four rolls, 25% chance of reserves so you statistically you should get 30 points a turn. Cheaper with Gha, speed 8 to help your undying army get to the front lines before the game ends, and potentially a massive army. I've been trying for awhile to build a solid competitive reserves team, it's hard to find the balance between boosting your chances of more troops and just bringing troops/commanders. Here is another Separatist take on reserves:

--Grievous's Droid Army--
57 General Grievous, Droid Army Commander
43 Wat Tambor, Techno Union Foreman
30 Nute Gunray
19 Monnok
17 Ghhhk
15 Lobot, Computer Liaison Officer
12 Gha Nachkt
5 Rocket Battle Droid
2 Mouse Droid

So only two rolls a turn but a 30% chance and Nute helps last minute tailor some options for you.
So thoughts on these teams or just the idea of reserve teams in general?
