During the 3rd age, PvP took a turn for the worst as reshuffle got "fixed" to help stop spamming dispels and jujus therein effecting grandmaster PvP, a very popular level at the time. Most of my friends have quit because PvP got less and less interesting as time went on. I feel that if KI brought back card copying using reshuffle we could use strong and cloak again. This in turn may bring people back and there may actually be a PvP community again. What they could do is make bad juju unable to be copied. They already fixed dispels with the dispel shield. I feel that it wouldn't hurt to do this and would make more interesting, original strategies available because this allowed you to forge a deck to counter your opponent.
