Your opponents play with their hands revealed.
When you search your library for a card, you don't have to reveal it as you find it and you don't have to shuffle your library afterwards.
Skip your next draw step: Search your library for a blue or black card, reveal it and put it in your hand, then shuffle your library. Activate this ability only during your upkeep and only once each turn.
