Vinny Scales, Kingpin

Mercenaries you control have trample, vigilance,
and "when this creature deals combat damage to
a player, scry that many cards."
{t}: Name a card. Target opponent guesses
whether that card is on the top of your library or
not, then you reveal the top card of you library;
if they guessed incorrectly, you may play that
card without paying its mana cost. Otherwise,
exile it, and you lose life equal to its mana value.
