Actually, it depends how you play them. Lamar can wipe out most 8 power opponents. Only the few having stop bonus ability and have a greater or equal power ratng can give Lamar trouble. Striker is good but only 6 power and any attack reducing bonus with right amount pills can remove him.
Hmmmm another comparison Brother? Well, that's easy, Lamar again is better. Eyrtonhas 8 power and if a lower powered card with stop bonus ability shows up, he's still 8 power. Two problems though, any mid to high Upper with bonus can give him trouble and Lamar or Flo could actually defeat him. Even Montanas. Also, 5 point damage is not high enough. If they would have given him 6 damage with a useful ability, he would be awesome..
