Urza's Chalice

Artifact, 1 (1)
Whenever a player casts an artifact spell, you may pay {1}. If you do, you gain 1 life.¹
When sorely wounded or tired, Urza would often retreat to the workshops of his apprentices. They were greatly amazed at how much better he looked each time he took a sip of water.
