Q: If I use Goblin Charbelcher and I don't have any land cards in my library what happens? Do I get decked? Does it cause a loop? A: If you don't have any lands in your library you reveal all the cards left in the library, then the Charbelcher deals 1 damage for each revealed card. Then you put all the cards back, in whatever order you want. Even if one part of an effect fails, the other parts will try to do as much as possible. Revealing the land is just a stop condition, it's not a requirement to deal damage (it doesn't say "if you reveal a land…").
