As of Mid-August 2017, Nissa, Vastwood Seer is selling for around a mere $6-7. Even her foil is only fetching about $18. While a multiplier of 3 is fine for a foil, one that is ubiquitous in Commander as Nissa, Vastwood Seer is likely to be much higher than that. Not to mention, this is a double sided mythic rare card. You would think her foil price would have a multiplier closer to 4, such as with Jace, Vryn’s Prodigy.
While not a big deal in multiplayer as a Commander (only about 250 decks on EDHREC), Nissa, Vastwood Seer does see play in over 4500 decks as a member of the other 99. While Borderland Ranger is a good card in that format, her planeswalker side is even more valuable in that format than in Standard. She’s also a very good Commander in 1v1, although that format doesn’t drive prices in the way that multiplayer does, at least not currently.
Nissa, Vastwood Seer does not transform into a planeswalker until you control at least seven lands in play. But Nissa, Sage Animist is worth the wait. Her first ability allows you to draw a card, and if it’s a land card, put it directly into play. That’s already pretty good. She can also create a 4/4 legendary token. But her ultimate is extremely good, which can untap 6 target lands, and turn them into 6/6 Elemental creatures permanently. While all of these abilities were good in Standard, there are far more opportunities for her to transform in EDH.
As a card that once peaked at $32, there’s plenty of room for Nissa, Vastwood Seer to grow. While it’s doubtful that she’ll hit $30 again without being in a surprise Top 8 appearance in Modern or some other Eternal format, her foil price could easily reach that again. That would mean her non-foil version would probably follow suit in price to about $10-12. It’s hard not to see yourself doubling your money on Nissa, Vastwood Seer in a few years.
While I wouldn’t necessarily recommend Nissa, Vastwood Seer as a target for price speculation, it is fairly easy to predict that her price will rise considerably as time goes on. It is fairly easy to say that Nissa, Vastwood Seer is a solid buy, especially if you’re planning on playing a Green Commander deck that would typically play a copy of her.
