I would like to suggest gameplay modes for PvP. For starters, how about "Last Wizard Standing". All 2-8 players battle it out and whoever is left wins a ticket.
The only problem would be is that this can go on forever especially if there are 2 life wizards left and no more attack cards to use. :-P Perhaps, putting a timer would be a better idea.
Thats what reshuffle card are needed for, Make sure to keep one in your deck at all times. Saved me three time in boss fights too.
(first commment/quote i have done ever) what if they have an auto reshuffle for duels and pvp like it takes 2 pips and it is a button like the pass button and the draw button and it takes one turn
