Anyway, one thing. Do not create Starter cards or Starter Bakugans in shop. It is not necessary to create them. You only create your own Bakugans you come up with. Bakugans ftom your imagination; your own Bakugans.
Card's color represents card's class. Blue color is lowest class. Green color is middle class. Red color is the highest class.
Card's color/class depends on how strong your card's effects are. If your card contains simple effects like 'gain 200 G' your card will be Blue. If your card contains a strong effect like 'reuse a card' your card will be Green. If you card contains a very strong effect like forcing opponent's power down to zero then card will be Red.
There are also special classes; White and Purple. White only goes with Starter cards. And Purple are Forbidden cards. Let's say you create 4 cards at 22:00 o'clock. You can create 4 new cards as soon as new day comes at 00:00. We normally wait 24 hours, but members and staff members are low, so I think we can allow you to create 4 more. But after that you need to wait until 00:00 to create again.
I am not sure if this helps. If you still have difficulties feel free to ask.
Blue card is a basic card... So it accualy means, that card isn't more than 0-200G. Green card is a good card... It also means that are special efect to enemy our ally. Reda card is a strong card.. It's is more than 200G.
I am not sure what you mean by those 'letters'. Where are those letters?
To evolve you must win 7 brawls, have at least 2 brawls without being disqualified or earning a strike, and have 3 stars in your profile. By the time you win 7 brawls you'll already have 3 stars anyway. Admin is strictly against pay-to-evolve policy.
