3 rulings from Wizards of the Coast
- 4 October 2004When being declared as an attacker, use the "not attacking" power and toughness. It only changes after declaration is complete.
- 25 September 2006The activated ability doesn't affect whether the land is basic or not. It overwrites any other land types. Being a Forest gives the affected land the ability "{T}: Add {G}."
- 15 October 2006Will not add or remove the supertype snow to or from a land.
