Plato of Athens

When Plato of Athens enters the battlefield, create {x} 0/5 Guardian creature
tokens, where {x} is the number of players
in the game. Guardian tokens you
control have shroud and "{1}, {t}: Look at
the top card of any library. You may put
that card on the bottom of the library."
"The measure of a man is what he does with
power." - Plato of Athens
