Chani, Water of Life Giver

Whenever Roxanne, Starfall Savant enters
the battlefield or attacks, create a tapped
colorless artifact token named Meteorite
with "When Meteorite enters the battlefield,
it deals 2 damage to any target." and "T: Add
one mana of any color."
Whenever you tap an artifact token for
mana, add one mana of any type that artifact
token produced.
