Mad Mountaingorger

Sacrifice any number of lands, destroy up to X
target artifacts and/or creatures, where X is equal to
the number of lands you sacrificed this way.

Whenever one or more land cards are put into your graveyard from anywhere other than the battlefield,
you may put up to one of those lands onto the battlefield tapped. This ability triggers only once
each turn.
One swing from its mighty blade cleaves the horizon
in twain.
