Terramar, the Earthstorm

At the beginning of your upkeep, you may put X
+1/+1 counters on target land, where X is the
number of lands in your graveyard. It becomes a
0/0 elemental creature that is still a land. If an opponent controls that land, it is goaded until
the end of your next turn.
{t}: Draw a card, then discard a card. If you
discard a land card this way, Terramar
deals 2 damage to each opponent.
