Innistrad is widely regarded as one of the best Magic: the Gathering sets of all time. Why not? It has plenty of strong cards: Liliana of the Veil, Snapcaster Mage, and Geist of Saint Traft lead the way. There are also really good enchantments such as Parallel Lives and Stony Silence, not to mention vampire queen Olivia Voldaren. But there are three cards that it seems are undervalued, and I’ll get to why they are.
While Parallel Lives is a card very popular in Commander, it has a strong chance of being reprinted in a Commander pre-constructed deck. Bloodline Keeper is a very popular card in Commander, too, as well as being one of the most popular Vampires in casual play. It even pops up in a Modern deck here and there. But what’s great about Bloodline Keeper is that it’s double-faced - and Wizards has already said that double-faced cards are a pain to reprint. So it could be quite some time before we see this Vampire Lord reprinted. At a buy-in of only $5 or $6 this is a good card to hold onto. The supply won’t last forever. Foils are also only around $8, which is crazy low.
Being a mythic rare and being double-faced really helps your chances at being a good investment. Garruk Relentless is played a ton in Commander and has even seen some fringe Legacy play. The only reason that he’s been languishing around $5 for so long is the supply is simply good enough. Like Bloodline Keeper, he’s a long-term investment. Most decent planeswalkers end up at least $10 in the long run, and while it may take him longer than Garruk, Primal Hunter to get there (being mono-green and therefore fitting into more decks) he will get there eventually. Relentless only needs to show up in a Modern deck that top 8’s a major tournament and supply will be gone in a hurry.
As a card you can get for as low as a quarter, you may wonder why this is a long-term investment. Well, there have been plenty of attempts to break this card, including an infinite combo deck with Heartless Summoning in combination with Altar of the Brood and Myr Retriever. Essentially, once you have one Myr Retriever in the graveyard, you can always get the other one back. WIth Altar of the Brood on the board, each time a permanent comes into play on your side, it puts the top card of your opponent's deck in the graveyard. If you can loop Myr Retrievers, you can simply run your opponent out of cards.
The synergy of having a card that makes your creatures cost 2 mana less for the low cost of losing -1/-1 is something that seems pretty breakable. Over time, there may be a card printed that makes Heartless Summoning combo even more viable. As that combo deck showed, it can win games if it assembles the pieces quickly enough. Considering you can hoard playsets of this card for $1-$2, it doesn’t hurt to sit on a playset or two long-term. You just have to have a deck make the top 8 of some major tournament, fluke or not, and Heartless Summoning could be a $5 card over night. Again, it’s very long-term, but it’s the cheapest long-term investment in Innistrad.
While Snapcaster Mage and Liliana of the Veil are the most desirable cards from Innistrad, keep these three in mind when you’re looking for cards to make up the difference in trades. The only way these cards lose value is a reprint. A return to Innistrad is probably the only way Bloodline Keeper or Garruk Relentless get reprinted. Heartless Summoning is one of those niche cards that probably won’t be reprinted anytime soon. So if you happen to stumble upon any of these cards, hold onto them. It’s likely you’ll at least double your money on any one of them, and with Summoning, possibly far more.
