Wizards after introducing a long-awaited mechanic return as a smaller theme in a set: Hey you know what this needs? A hoser.

Realtalk, I think it is important to introduce a tangible reason to not run snow lands. There were cards before, like Freyalise's Radiance, but they weren't good because they only worked against snow. Reihane is a card I would use in appropriate decks even without the line about snow, so she gives snow basics an inherent downside to balance out all their inherent upsides.

Without her, many players would feel obligated to run snow basics rather normal basics, so as to cash in on these marginal upsides. Now these marginal upsides come with a marginal downside. This make using normal basics a deck building decision, rather than a deck building concession.

This further rewards and provides justification for people who particularly like using basics they have collected over the years. Because this card exists, I feel much more confident in my decision to use amonkhet islands in my Unesh deck, because the risk of reihane is greater than the benefit of scrying sheets, whereas my Gitrog deck uses snow-covered forests (and a snow-covered swamp) because it makes Into the North into a better rampant growth, that can also search for my dark depths.

Thanks for coming to my ted talk.
