Frostlands Watcher

When Frostlands Watcher enters the battlefield,
you may look at the top X cards of your library,
where X is the number of snow permanents you
control. Reveal up to one card from among those.
If it's a snow card, you may cast it without
paying its mana cost until the end of your next
turn. Otherwise, put it into your hand, then
shuffle your library.
At the crown of the Smoke Peaks, Orcish and Elvish
tribes gather in peace to worship the winter.
