Starborn

{3}{w}{u}{b}
Whenever Starborn is dealt damage, you may regenerate another target creature.

Whenever Starborn attacks, you may search your library or graveyard for an Artificer or Machine card, reveal it, and put it onto the battlefield tapped and attacking. That permanent deals double damage until end of turn.

"Born in the furnace of stars, wielding the power of forgotten worlds."
