If you buy a card on the market, without breaking any rules to get it, then that cards yours now, Its usable and sellable, It dosnt mattery where it came from in the past we wont remove it from you.
We only take action against the player or players who broke the rules.
Next up are the weekly missions since each clan has 1 arcade ld and 1 mission ld.
once you have lds EFC decks aren't too expensive and you should definitely be able to tweak your deck based on bans and unbans with the rewards you get from just playing the game.
