Reveal the top five cards of your library and separate them into two piles. An opponent chooses one of those piles. Put that pile into your hand and the other into your graveyard. Create a 0/0 colorless Thopter artifact creature token with flying (This creature can't be blocked except by creatures with flying or reach.), then put a +1/+1 counter on it for each card put into your graveyard this way.
