Rulings

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.
If the top card of your library changes while you're casting a spell, playing a land, or activating an ability, the new top card won't be revealed until you finish doing so.
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.
A colorless creature on top of your library never gives a bonus, and a colorless creature on the battlefield never gets a bonus.
