Lea, Glorg, and Kerry are commonly used.
Also affective are Wesley, Buckler, Shirley (but only I seem to like her) and Sue.
As Rescue, you will nearly always struggle against SOB. To counter, use cards with 6-7 power and good abilities (like the ones stated above) and learn to bluff effectively.
Also, Pam makes a decent wall (with 5(?) ) damage and +8 attack.
Pira Night onyl remove your bonus so cards that don't rely in their bonus should do good. Rescue has pretty good cards like : Kerry , Steve and Pastor are good defensive bluffers that can win you duels, no matter what clan u are against. Also Cliff and Antia are good cards you should have in your deck. Oh, and dont listen to people telling you that Pam is good, she isnt, she sucks. You can make a good Rescue deck without her.
Simple solution: Don't use Rescue.
If you want to try and win, I can tell you it's going to be very tough, especially with a star disadvantage as Rescue lack the high base power to compete against SoB. Sledg is good, and Cliff's damage and SoA is still there.
