I'm new to the game & was wonder that, are these cards perma banned from this mode & such i shouldn't plan to put them in my deck or do the bans change frequently enough to go ahead & put them in my deck & just have a plan B incase they get banned again?
On that first link that LOA Yellow posted, you see the characters on top are the temporary ones that players voted on the previous week, and on the bottom section are the cards that are permabanned. The permabans are updated maybe 2x a year. Unless a specific card is way overpowered.
The 2nd link shows which characters are eligible to be temporary banned next week. They're supposed to be the top cards from the top clans last week, along with what was banned the last week. It's also where you would cast your votes for what to keep or ban, if you have votes from the previous week. A card needs 5% of votes, with a majority being negative in order to be banned.
