Okay - I've been away for ages and there seems to be some new concept 'standard' cards... i don't really know what they are.... but it seems virtually none of my cards are... 'standard'. Could use a little help to understand what this all means and... i don't really understand why it's in the game.... Anyone want to explain? : I tried searching for it but no clear answers :
you should read the link before posting anything..
Create a list of characters called "Standard" which will be reset half-yearly.
In this list you'll find
"all characters (and LD too) released within the =="three last years before the update" ===,
Leaders, starter deck characters and characters released after the update. You'll find 13 to 16 characters in each clan. New clan will keep all their characters.
that's the answer
to answer why: because they want to make a balanced room without any strong old OP cards like Jackie Cr, Zatman, etc
