seasonal mode, overused cards, way how to change it

[nehu]

hi,
i like to play seasonal mode at most, but as anyone, i feel there is not much variability after first few days in each month

it would be great, if players could choose each day / week some card/cards to be banned for rest of the month in seasonal mode

something like poll to choose from most played cards in won matches

then each day / week, there could be fresh challenge in it

hardly to be implemented in the game, but it would be nice
