Avatar of Final Judgement

Split Second, indestructible.
When you cast Avatar of Final Judgement
each player chooses a number of lands he or she controls equal to the number of lands controlled
by the player who controls the fewest, then sacrifices the rest. Players discard cards and
sacrifices creatures, artifacts, enchantments and planeswalkers the same way.
Exile all graveyards.
If Avatar of The Last Judgement would leave the battlefield exile it instead.
