@80 no, that's not the case... i've had some cases of fighting the same opponent twice in a row, so i've been able to see more than 4 cards from their deck, and their total star count was definitely higher than 23*.
the magic number seems to be 350 battle points in a tournament, past which the system starts to match you with opponents at random, regardless of star count, but it seems to prioritize either 30*+ decks or people currently in the top 10. so it's much harder to make it past 500 under these circumstances...
also, i wish the staff would put penalties (at least -5) on Avola and Uranus, i'm just sick and tired of seeing them!
But forcing the player to click on every character, or to manually check all the characters in his deck through the list in the Tournament is pretty brutal, especially with some of the more obscure penalty characters (i.e. Slyde).
Maybe put it as an additional column in My Collection Pro?
And at least mention in the My Deck menu, near the Deck Formats, that the deck "contains penalty characters".
And maybe show a list of those characters.
In regards, to the penalties still not being enough to deter people from using cards the likes of Ambre. How about giving the player who meets these cards a slight bonus in addition to the existing penalty on those who use them? Something like...
Ambre +7 (For the record, I use Ambre. But yeah, it gets tiring to meet her 80% of the matches in DT)
Type A +5
Type B +3
Type C +1
If both player in a match have penalized cards then the bonus is annulled.
