Dangerous Voyage

At the beginning of your upkeep, sacrifice a
creature. Then, create a Treasure token.
Whenever you sacrifice a creature for the first
time during your turn, reveal the top card of
your library. If it's a land, put it on the battlefield.
If it is an instant or sorcery spell, put it into your
hand. Otherwise put it into your graveyard.
If you can't sacrifice a creature, sacrifice
Dangerous Voyage.
