In my opinion, we really need a graveyard. Where discarded and killed cards go. I've been talking about it since playing it with my mates. It's great to keep an eye on what cards are gone. What's used. How many left. The little timeline on the side is cool, but you have to scroll back and forth to see things. There are many cards I still have not learnt by heart and will need to click on it to expand and read. Having both would be great. Not only that but I've met a few decks which use The Rekindler to bring for example multiple Lux's from death only when I killed her once. I think it's unfair that this can be done. If there is only one champ in the graveyard or dead, you can only bring that one card back. Only be able to revive what has been discarded or dead.

EDIT: Having to bring up the card from the timeline just obscures the board. It's so bad that I would hear sounds only to be some what confused as to what just got played or transpired. Then having to scroll down the slow timeline and try to make sense of things, but then not know what card this is to make it bigger to obscure again.
