Fountain of Youth

At the beginning of your upkeep, scry 1,
then draw a card.

{5}, {t}: Target opponent's life total becomes 0 and your life total becomes equal to your starting life total. Activate only if you control an artifact named Two Silver Cups and an artifact named Tear of a Mermaid. Sacrifice Fountain of Youth at the beginning of the next end step.
A single sip restores what time has stolen, but at what cost to the soul?
