Displaying Deck Statistics at the end of a match.
This will actually be very helpful because we can not only deduce the effectiveness of the deck but also understand (and then fix) the problems faced while using it. Basically, it breakdowns the deck performance and gives us an analysis.It may include something like:
Amount of damage done/recieved.
No. Of cards drawn.
No. of energies/items/supporters used.
