Maaike, the Tidiness-Queen

When Maaike, the Tidiness-Queen enters the battlefield return target permanent to its owners
hand, then 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.
