Whenever Lisburne, the Fearsome Vessel deals damage to a player, you may prevent that damage. If you do, create X colorless artifact Gold tokens with "Sacrifice this artifact: add one mana of any color to your mana pool", where X is the amount of damage prevented, and you lose X life.
At the beginning of each end step, if you have created 10 or more Gold tokens this turn, transform Lisburne, the Fearsome Vessel.
