no guesswork of summoning trap

You may play an additional land on each of your turns. Play with the top card of your library revealed. You may play lands from the top of your library.

If a creature spell you cast this turn was countered by a spell or ability an opponent controlled, you may pay rather than pay this spell's mana cost. Look at the top seven cards of your library. You may put a creature card from among them onto the battlefield. Put the rest on the bottom of your library in any order.
