If you are in the NA server, you can pm me in game (Deuce), and we could run a raid if you wanted to see how they are. I've tried them all each a few times. I can understand not comparing them to big plastica/rita/grutin, but why not compared with worker/baalride since they are all 1* cards?
Also how can you determine if they are any good if you don't compare them to other cards? Like the 2 star card Shadow Dancers gives 13% atk dmg at T3. If it's the only card available, obviously you would wear it since it's better than nothing, but compared to all the other available akasha cards, it's trash. So same thing goes for all the cards you've listed. Why bother with them when you can use worker/baalride?
