Super cool card.
Probably very powerful since it costs 3. The lands can both attack and block because of vigilance and the "until your next turn." We're entering the era where planeswalkers that cost 4 are difficult to find room for in any non-Standard format (
@Jason Waddell please don't tag anyone to have them bring up a Common format or stuff like that). If you want to include planeswalkers in your Commander, Modern or Legacy deck, it better cost 3 mana or be one of the best of the best 4 mana value.
For my cube it doesn't work although it has some key 5-color text because it's a planeswalker and I cannot include those too early.
Are we getting a card spoiled every day? I thought it was next week they kicked things off.
