Summoning Trap 139 - Modern Masters 2017 [MM3]

Summoning Trap

If a creature spell you cast this turn was countered by a spell or ability an opponent controlled, you may pay 0 rather than pay Summoning Trap'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.
