If a spell or ability would cause you to shuffle your
hand into your library, you may discard your hand
instead.
(This occurs after other shuffling effects)
If a spell or ability that causes a player to discard
2 or more cards and then causes the same player
to draw 2 or more cards, that player may draw
that many cards minus one if they do then they
may return up to 1 card from their graveyard to
their hand.
