Starscourge Radahn

Whenever Starscourge Radahn 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 "Tap: Add one
mana of any color."
Whenever you tap an artifact token for mana,
add one mana of any type that artifact token
produced.
