This is really up all of the decks that i use for ELO are being recked by the cards getting banned by the staff why make cards that people pay for and trade to get when they will not be permited to be used in the ELO mode the next week when they get banned by the staff. i cant even play ELO this week because all the good decks i have and use have some cards that are not allowed to play in ELO. when only some cards are banned from certain clans there are less cards to use from that type. If no cards are banned every one can have the same chance but with only a few here and there banned it is not far. .
I'm guessing you mean the Temp bans rather then the Perma bans.
The Temp bans are not permanent. Those cards are going to be allowed again. And are still usable in DTs without a -2 BPs. You can always check which cards are going to be Temp banned by looking at the banned characters page and checking the weeks ahead.
