I would like to see a modification to the elo banning system, whereby players are permited to use elo banned card, at the expense of a number of stars.
It seams to me that some of the banned cards are far weaker than others, and as such they should cost just one extra star, and those very powerful cards should be worth two extra stars in elo play. this can be seen as a post modification to the star count of card in order to balance cards and clans acordingly
Good on paper, but I'd really hate seeing Jackie or GraksmxxT in ELO even if the person had to use 6 stars to put them in. Unless the rest of your deck is very poorly made/drawn, it is very difficult to play against some of the ELO-banned powerhouses. 5 stars for Wee Lee or Ratanah might be worth it, but some of these other cards are just too powerful to face, no matter how many stars they are.
