With the last two previews I'm seeing potential for near endless swarms of troopers, particularly on the Imperial side with Weiss.
With the Weiss pack we saw Endless Reserves: Action: Choose a defeated friendly Trooper and place it in an empty space adjacent to another figure in its group. Then, shuffle this card back into you command deck.
And now with the Rebel Trooper pack we have Reinforcements: Use at the start of a round. Choose 1 of your defeated Troopers that has a reinforcement cost of 3 or less. Place that figure adjacent to any other figure of its group.
You can have 2 Reinforcements for 4 points plus the 2 points for Endless Reserves, which is a fair chunk of your command card budget, but the potential for keeping points on the board is awesome.
Weiss plus 4 Stormtroopers could be a popular list for attritional wins.
