I'd like to see Starkiller in IA. I definitely like the idea of him having separate Deployment Cards for both Imperial and Rebel use.
His unique command card could be Force Repulse (2 actions: Roll 2 Red dice. Deal that much damage to each character within 4 spaces and push them 4 squares).
Why not just "Defeat all characters on the board."
Starkiller is the most OP person in Star Wars and is only popular among those who don't know what the word 'balance' means.
This sounds like a child whining. How is someone OP in Star Wars, that doesn't even make sense, OP in a certain game maybe. This ability is strong and would probably have to be toned down to just adjacent spaces, but it's a command card so it's a one shot use assuming you draw it and don't strain it off your deck.
Your second sentence just makes you seem like a **** who has to put people down. Good luck with that.
