Quote from hyalapterouslemur »Strictly better than a diamond. Can be made better with "snow matters" cards, whatever those are. (Especially since the snow hosers focus on lands and are generally crap.)
Definitely worth putting in any mono deck. Or even a two-color deck. The real question becomes "How many signets can I run?"
The only snow-matters card that should be ran that benefits from this is Scrying Sheets, though arguably you could also note Heidar, Rimewind Master as a commander and Mouth of Ronom but yea.
It's a good mana rock especially for mono colour decks, gets even better if you coughed up for a snow manabase. 9/10 in snow-mono-colour, 8/10 outside of it.
