Mayada, Head of Potions

Vigilance
Whenever you cast an artifact spell, brew.
(Choose one at random from Life Potion, Fire Potion,
and Scrying Potion. Then create that token.)
Whenever you sacrifice an artifact, create a 1/1
white Human creature token. If that artifact was
a potion, create two of those tokens instead. This ability triggers only once each turn.
