Until end of turn, cards you own that aren’t on the battlefield lose all card types, costs, names, and abilities and become red sorceries named Missile that cost with “Missile deals 2 damage to any target.”
If Bombardment is somehow cast while another spell is on the stack, that spell becomes a Missile. Since that spell has no target chosen for its spell ability, it won’t resolve. This is true even if that spell had a target for an ability it had.

If any portion of your library is randomized, those cards become new objects that aren’t Missiles.
