Gerode: You'd have to get the red mana somewhere, and it would probably be easier to just use Goblin Bombardment. Otherwise, you might have to use Carnival of Souls and Soul Warden and Celestial Dawn to generate the mana, along with something like Verdeloth to generate the tokens.
The real question here is Goblin Bombardment vs. Deadapult.
IMHO, Deadapult is better in a deck designed to generate time advantage, whereas Bombardment is better for a deck that doesn't have mana to spare or is trying to set up some combo to sacrifice en masse. Both have their uses. However, due to its restrictions on what can be sacrificed, I think Goblin Bombardment is probably at least a little better.
