2013-04-15: The top card of your library isn’t in your hand, so you can’t suspend it, cycle it, discard it, or activate any of its activated abilities.
2013-04-15: If the top card of your library changes while you’re casting a spell or activating an ability, the new top card won’t be revealed until you finish casting that spell or activating that ability.
2013-04-15: When playing with the top card of your library revealed, if an effect tells you to draw several cards, reveal each one before you draw it.
