Oh. It's impossible to be devoted to snow at all with existing cards.

It's also impossible to be devoted to snow with this card, since it isn't a 'Snow Land'. ;)

I see what you did there, though.

Even if this was a snow land, that wouldn't help because this doesn't have a mana cost. A board full of Scrying Sheets, Snow-Covered Islands and Ronom Serpents still won't make you devoted to snow, because the only things in their mana costs are .

Meh, I'm sure some will turn up; on multiverse if nowhere else :)

Adding snow mana just results in adding colorless mana; the resulting mana isn't snow unless the source is snow. (In other words, "add " is the same as "add ", and it is also the same as "add ". See rules 106.10 and 106.11.)

Yup; jmg already pointed out this card won't work for that reason; and Alex pointed out why it won't for a second reason. So this card fails.

Read aloud, though; to get the actual reason for the card :)

O, OK, now I understand why you did this.

(Well, it still adds , and presumably "devoted to snow" means you control a permanent with in its mana cost (that is my guess of what it means), so the card still works, it just won't produce any snow mana.)

Amusingly, in the intervening years they printed Icehide Golem and Arcum's Astrolabe, so if you try really hard it would be possible to get your devotion to snow up to 4 or 5.

...Hang on, this doesn't actually specify what level of devotion is needed. Compare Heliod, Sun-Crowned which asks if "your devotion to white is less than five". So I guess a single Arcum's Astrolabe would mean that you're devoted enough to Snow for this? Maybe that round thing in the middle is an apple.
