I believe the card chosen is the one with the highest attack out of all three attack units.

I'm not sure if they just need one win or three, but I know that if a member's last battle was a loss, they won't be assisting you.

The "Connected with" message tells you the last person who won a battle before you started yours. It might be useful for setting up combos with your alliance mates.
