Aphelios, Soul of the Lunaris

When Aphelios, Soul of the Lunaris enter the battlefield, search your library for a card named Calibrum the Rifle, Severum the Scythe Pistol, Gravitum the Cannon, Infernum the
Flamethrower or Crescendum the Chakram and
put it into your hand. Then, shuffle your library.
