The Roads Diverge

Search your library and/or graveyard for up to 4
land cards or 3 nonland cards. Your opponent
separates them into two piles without looking at
them. Put one pile in your hand without looking
at them, and the other in your library. Shuffle
your library thoroughly.

And once more, the roads diverged in front of
him, and he was forced to choose blindly and
hope for the best...
