Spelltable - Card Count Tracker
Making Spelltable as "Real World" accurate as possible would aid the user experience and playability. Consider the addition of a means of tracking the number of cards in a given zone: library, hand, graveyard, and exile. Perhaps each draw could be tracked for cards in hand/ graveyard depth /cards exiled /and playable exiled cards. Auto-scanning cards placed in graveyards and exile would be ideal.
