Do you actually expect to win 2 combats in a turn with no cards?!?
Your regular play group is very strong, if that's actually an expected outcome for you.
To be fair Crimea can do that. Their Scouting Ability means that either they will always have a card whenever they fight or that neither player will have a card. In fact if they steal their opponents highest card they automatically win.
Basically as long as they have 7 power with scouting they will win any 1 v 1 fight that:
A. Their Opponent has no cards
B. Their Opponent has 1 card
C. Their Opponent has cards of the same value
D. They Steal a proper card from their opponent
So it's not completely farfetched although it does rely on opponents who leave lone combat units around like sitting ducks.
