Ok, I had this really cool idea. What if, When you went to the pvp screen it had an awesome that said "Battle Characters" or something. For example, if you had 6 characters you could click this option and select 3 of your characters to be on one team, and another 3 to be on another, you could select their decks modify them etc, and then begin to duel of your characters fighting each other in a 3v3. They could be controlled by cpu or by the user. What do you think?
If this gave Ranking Points, lazy PvPers would have 3 Transcendeds fight 3 of their Novices, thus attaining Warlord with no skill required. It would be abused in this manner for as long as possible. Sorry, but I disagree.
It would have to be practice only. It would be too easy for you to rig the other teams decks to lose. Also the AI isn't exactly intelligent... It's nice but it does some pretty random things. It wouldn't really be PvP either.
Now a boss that had one or two minions that were copies of you. That I would go for. You can't cripple your deck to beat your copy easily, because the boss is there. You also have to decide which is more dangerous, the boss or your double(s)
