While Weathered Wayfarer has seen occasional play in the Modern format, this creature's value is most appreciated in EDH. The Wayfarer sees play in over 6000 deck lists on EDHrec, and there isn't one commander that favors Weathered Wayfarer.
The reason for this is probably the simplicity of the Wayfarer ability. For just one White mana, you can tap Weathered Wayfarer to add any land card from your deck to your hand. Plus, Weathered Wayfarer is only a one drop creature to begin with. Basically, as long as decks use white mana and play lands, Weathered Wayfarer will be a great way to get some early card advantage.
The supply of both printings of Weathered Wayfarer isn't all that high. Buy list prices weren't extremely high in 2017, and there was an over 40 percent spread between retail and most buy list prices. This was because despite being such a good card, most vendors don't seem concerned about running out quickly. Looking at the rapid growth of EDH, however, the supply wouldn't last. In 2018, the spread dropped to around 20 percent and prices of the card rose by around that same amount.
There is a real chance that Weathered Wayfarer could be reprinted, however. The Wayfarer doesn't have any flavor restrictions that would keep it from being in an expansion set down the road. It definitely makes sense in a Commander deck. However, this card would have to be printed on a.major set release to see its value tank in the long-term, however. A lot of players will soak up the supply of it in Commander decks, because most players will just keep their copies.
As far as foil prices are concerned, Weathered Wayfarer is probably a good one to pick up. 9th edition foils push $30 and Onslaught foils about $28. That's not high considering how playable this card is in non-rotating formats and how much rarer foils were with those sets.
Magic Online Cues
With the rising popularity of 1v1 Commander on Magic Online, Weathered Wayfarer nearly doubled in price online. It wasn't really expensive there to begin with, and it had an additional theme deck printing on MTGO. But being around 0.5 tix and jumping to 1 ticket a copy in a few days is obviously a sign of something.
There are Breya, Etherium Shaper decks that play Weathered Wayfarer. She's one of the top commanders in the 1v1 Commander leagues right now. The Wayfarer is good in a lot of 1v1 Commander decks, actually. Obviously, the value is high in multiplayer EDH, as well. But it seems that the 1v1 Commander demand is driving the price online. If Wizards adopts 1v1 Commander as a sanctioned competitive format in paper Magic (who knows, it could happen!) then Weathered Wayfarer’s price would probably spike.
Potential Price Spike and Reprint Risks
Honestly, the multiplayer EDH community in paper Magic is probably enough to make this a $20 card some day, especially if there’s no reprint incoming. But so many people are probably holding their copies right now that if there is a price spike, it could right itself very quickly.
When I think about reprint risk, I’d definitely be investing in a foil copy if I needed one for an EDH deck or if I wanted to try it in Modern Death and Taxes. It’s also a pretty fair deal on Magic Online at anywhere around 1 tix; the supply isn’t great there, either. I really like Weathered Wayfarer going forward, and this is definitely a card that without a reprint will become $18 to $20 very quickly once the current supply runs dry.
If Weathered Wayfarer does get reprinted in the near future, I’d definitely be picking up the new copies. This is just a really, really solid creature that does something that will be good forever.
