Whenever Roxanne, Starfall Savant enters the battlefield or attacks, create a tapped colourless
artifact token named Meteorite with "When
Meteorite enters the battlefield, it deals 2 damage to
any target" and "{t}: Add one mana of any colour."

Whenever you tap an artifact token for mana,
add one mana of any type that artifact token
