@cdmnky is this just... the same picture twice but once sideways?
I also rather imagine that MTG hasn't bothered trying to fille patent infringement lawsyuts against other games (such as YuGiOh) that have a similar card manipulation mechanic because..... well if they did that they'd waste a hell of a lot of money trying to defend their patent only to have the patent ruled invalid...
@Felthry @cdmnky I really don't think it is but no one has bothered to challenge it
