Data checksum?
Looking at the set 0 cards, all Vision Single cards have an even count of 1 bits (which total from 8 to 24). It's not simply a parity bit, though, because when you include player-created cards (which have a use cost), they appear to have a similar mix of even and odd bit-count cards, yet are all valid.
Still, there's some simple significance in how the Vision Single cards encode their trailing bits, somehow making the card "valid" to the game. --FeralKitty (talk) 22:18, 4 March 2011 (UTC)
