Vampiric Swarmer

When Vampiric Swarmer enters the battlefield, create two 1/1 white vampire creature tokens with lifelink.
{1}{w}{b}, {t}: Foresee once for each vampire
you control. (Guess a cardtype, then look at
the top card of your library. If correct, reveal it
and draw that card. If wrong, place it at the bottom of your library.)
