Dryads of the Luxor

Players can't look at or reveal cards from the top
of their libraries. Any player may pay {2} for that player to ignore this effect until end of turn.
At the beginning of your upkeep, you may reveal the top card of your library. If it's a land card, put that card onto the battlefield and you gain 2 life. If it's a nonland card, create a 1/1 green Snake token with deathtouch.
They bestow the gifts of both poison and cure.
