Bo Lin, Earth's Fury

At the beginning of your upkeep, reveal the top
card of your library. If it's a land card, put it into
the graveyard, then Bo Lin, Earth's Fury deals
damage to each opponent equal to the number of
lands in your graveyard. Otherwise, put the
revealed card on the top or bottom of your
library.
{r/g}: Put target land in your graveyard onto the battlefield.
