Ö, teacher of modesty

Once per turn you may reveal your hand. If you
do, and all revealed cards are of the same rarity,
you may put a creature card from your hand into
play, without paying that cards mana cost.
Whenever a non-token common creature leaves
the battlefield under your control, you may create
a 2/2 white human monk creature token.
{1}{t}: Discard a rare or mythic rare card.
