Kirin's Bluff

As an additional cost to cast Kirin's Bluff, pay X life.
Name X different card names. Target opponent guesses if at least one card with that name is in your hand or library. For each correct guess, they may draw a card. Otherwise, for each incorrect guess, that opponent loses 2 life and you may search your library for a card, put it in your hand, and then shuffle your library.
