Discard Controversy
To reiterate, at the start of the tournament Effel declared that discards will immediately be killed and placed in the dead wood. (This is the pile that includes mucked hands but excludes burn cards.) Those cards will be shuffled back into the deck if needed. However, burn cards will stay down on the table for the duration of the hand.
Howard Lederer thinks all discards should be kept separate from mucked cards; you should never have the chance to get back the same card. Typically, in 2-7 Triple Draw, the discards are kept in a separate pile from the muck for this very reason. However, under Effel's rule, it's possible that a player could receive in the third draw a card he discarded before the first draw.
Greg Raymer, and several other name pros, are even more unhappy with the chance to receive the same card in the same round. They all agree that there should never be the chance for such a situation to occur. However, again, under Effel's rule, each player discards, and those discards are immediately killed and placed in the dead wood. If the stub proves insufficient to cover all draws in that round, the dead wood is shuffled and then the draw is completed.
