First note, in this game, Score Attack is WAY easier than in the last two games, so beat everyone is not as frustrating as in past entries. To make the process easier use Iron Tager: the strategy is to use any D attack to the opponent to magnet them and then trying to lend his B command grab, making huge damage and probably draining his life with 3 or so. Hold the b button while making the grab to attract them to the move easier, try also to use his Overdrive to attract them to you automatically or use his command grab Distortion Drive to blow 50% of their life, whenever you land a command grab, approach them with ↓D to be close to when while they are waking up off the ground. You can also try air B into command grab to land it easier, but they can tech out of it pretty easy. I choose the list with Bang at first because I think the are easy to manage, except Noel and Jin, specially Jin; because they have projectiles and very fast tools that makes approach them harder, make sure to approach them with ↓↘→ A or B (mainly B) because this move is inmune to projectile and stun the opponent a large amount of time If it hits. Follow this steps wisely, and also remember to block sometimes or you will be losing life easier, be careful and good luck!
