Dann kommt am ende der bibliothek Schaden = gezeigte Karten.
Q: I would just like to have a clarification concerning the Goblin Charbelcher. What happens if there are no lands left in the library at the time its ability resolves?
A: The ability isn't dependent on finding a land - it's dependent on how many cards you reveal. The stopping point is either a land or the end of your library, whichever comes first. It'll deal damage equal to the number of cards revealed, which is equal to the number left in your library. You'll then put the revealed cards on the bottom of your library (which has no top at the moment) in any order, meaning you'll get to stack your deck.
