Wow ... I'm shocked!
Ness, I couldn't agree more! The "when" of its use, or "if it should even exist" have never been discussed on any of the forums that I remember. Perhaps it was a practice that happened which was not fully sanctioned by TPCi (or PUI), so we didn't hear about it's use.
If this becomes common use, it would change things up substantially, making decks viable that weren't viable before. I can see how people are going to take advantage of this now that would have never considered a low basic count deck beforehand. Is this a practice that we really want to encourage? Not in my opinion. However my opinion doesn't count for much. :biggrin:
It has been discussed in forums that you have had access to. Can't help with the memory issue.
It is not only sanctioned by POP, it is their solution.
It is not something that should be used very often.
It is not used very often, as can be seen by the fact that most players are unaware of its existence.
I have done it or had it done (at events that I've run or HJ'd) less times than I can count on the fingers of one hand.
That's how often it should be used. It should be a "last resort", not a "first action".
If it is used after only a couple of mulligans, then yes, it could be seen as potentially abusable.
However, if a player has mulliganed over three times, the first thing I would do is to monitor their shuffling. If I see they are doing a full shuffle each time, involving multiple riffle or other kinds of shuffles that take 30 seconds or more per shuffle, the first thing I would do is to mandate a truncated shuffle. After all, the cards are randomized already. We're just looking at groups of 7 cards at a time. We're not moving the cards around (declumping) or anything, so extended shuffling is not required each time.
If they have a problem with shuffling quickly, I will shuffle for them!
If, after a few more draws, the player is still getting mulligans, then finally I will declare the judge ball to resolve it. By this point, the opponent has probably had the option to draw upwards of 6 or 7 additional cards.
