Keep minimum deck size to 40 but allow players to slot up to 60 cards. This change would inherently increase deck diversity by allow a bigger variety of cards to be played as well as allow certain types of archetypes which require a large number of specific synergistic cards to exist.

The max deck size of 60 cards was a product of physical limitations from physical ccgs that do not need to be carried on through the digital medium which does not have the same limitations.
