Maokai, the Twisted Treant

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, create
a 1/1 green and black Sapling creature token with "{t}, Sacrifice this creature: Target
player loses 1 life."
"Beset by spirits, my home laid to waste!...And
they call me twisted."
