The Soul Stone

The Soul Stone does not count as a card in your
deck.
At the beginning of the game, exile The Soul
Stone face down from your library.
At the beginning of your end step, you may
sacrifice a creature. Then, if you control no
creatures with power 4 or greater, put The Soul
Stone face up onto the battlefield under your
control.
{1}{t}: Sacrifice The Soul Stone: Create a 10/10
Spirit creature token with hexproof and trample.
