Ssusyrissus of the Deeps

When Ssusyrissus of the Deeps enters the battlefield or attacks, create a treasure
token.
{1}{u} Sacrifice a treasure token:
Draw a card.
Beneath the seas of Thain lies a massive horde of
gold and treasure, the plunder of dozens of ships,
guarded jealously by one of the last true dragons
to call the island its home.
