Ayn Rand

{2}{b}, Sacrifice a creature: Target creature gets +X/+Y until end of turn, where X and Y are equal to the sacrificed creature's power and toughness.
{6}{b}{b}, {t}: Exchange control of two target nonland permanents. Ayn Rand doesn't untap during your next untap step.
"A creative man is motivated by the desire to achieve, not by the desire to beat others."
