Forbidden Treasure of Olomotha

At the Beginning of your upkeep, each of your opponents may create a treasure. For each
treasure created this way, you may create a 1/1 Skeleton Pirate token with Boarding Party 1
As long as any player controls a treasure on the battlefield, Skeletons you control get 0/+1
Young men with hearts of greed pillaged the treasure
but the more they took, the less they felt. Before they
knew it, the gold was gone and with it, their souls.
