Hi,
can you plz add the function that you can mark cards at the starting hand.
I think about:
click on one card > it gets coloured, if you click twice it gets another colour, if you click a third time the colour is back to standard
first colour is for permants on the battlefield
the second colour is for played cards in the graveyard
instead of colours it can also be a word notice like: first click > battlefield, second > graveyard, third > no notice
