I couldn't reproduce this exactly, but for me it was working as Stassy reports when I cast it, except I didn't have to pay anything for my lands (which all survived- no message box, nothing. Just a bunch of the AI's lands flying into the graveyard). When the AI cast it, it seems to work like a one-sided Armageddon against me, with no dialogue box or anything. Also, all of the AI's remaining lands were destroyed except for the three plains I gave it to use to cast Cleansing. Possibly related to the sacrifice-multiple-lands bug? Neither the AI nor I had any lands in hand during any of this.
