Erich, Juvenile Charlatan

Hexproof
At the beginning of your upkeep, each opponent
turns all nonland permanents he or she owns
face down as 2/2 colorless creatures until the end
of turn. Then choose up to one random creature
for each opponent to sacrifice.
His charm and wit made the enemy question their
identities, then his devilry randomly eliminated his
foes during the resulting chaos.
