Faerbrough, Ambush Master

When a creature you control enters the battlefield, if you cast it, you may pay 3 life. If
you do, reveal the top three cards of your library. You may put a land card from among them onto the battlefield tapped. Put each other card onto the
bottom of your library in any order. Then, if
you have 10 or less life, Faerbrough, Ambush
Master deals damage to target creature equal
to the number of lands you control.
