High Peak Village

At the beginning of your upkeep, for each basic mountain you control reveal the top X cards
of your library, exile a permanent card from
among them, put the rest on bottom of your
library in random order. You may play that card
until end of turn, if you do, sacrifice it at the beginning of your next end step. It gains haste.
They say it's dangerous to live up in the mountains.
But sometimes I just need to get away.
