  Official Ruling
  Your maximum hand size is checked only during the cleanup step of your turn. At any other time, you may have any number of cards in hand.
• WWizards of the Coast2009-10-01
  Official Ruling
  If multiple effects modify your hand size, apply them in timestamp order. For example, if you put Spellbook (an artifact that says you have no maximum hand size) onto the battlefield and then put Recycle onto the battlefield, your maximum hand size will be two. However, if those permanents entered in the opposite order, you would have no maximum hand size.

  Official Ruling
  To play a card means to play a land or to cast a spell that's a card (and not a copy of a card).
