The Destruction of Kharbranth

Each player chooses a number of lands they control equal to the number of lands controlled by
the player who controls the fewest, then sacrifices the rest. Players discard cards and sacrifice creatures the same way.

"Kharbranth. Preserve only Kharbranth. You may destroy all other nations. Just leave my city. It is
what I beg of you."
