Taliyah, the Stoneweaver

Landship—At the beginning of your
upkeep, look at the top card of your library.
If it's a land card, you may reveal it. If you
do, Taliyah, the Stoneweaver deals X
damage to any target, where X is equal to
the number of lands you control with the
same name as the revealed card.
