On MTGA "Keeping 7" cards verses "Discarding" after you have more than 15 cards in your hand. I'm used to discarding to handsize, due to most games only requring that. But in cube you can chain off powerful spells to allow you to have a lot of cards in hand. An example during cube, I drew up to 15 cards in hand. I'm used to discarding to hand size so when I picked the lands I thought were going to be discarded, it was actually the opposite and I discarded my spells instead. The prompt does say something along the lines of keep 7, but I think that is confusing because really in clean up you are discarding the cards you choose. So consistency would be nice.
