Ever since Secrets of Strixhaven became legal last week, the set has been generating increasing buzz in the Magic market. Considering that players can finally use the new cards instead of just theorizing, this isn't surprising. What is truly surprising, however, is that this time it's the main set driving demand, rather than the five precons. In particular, the new Elder Dragon cycle is pushing prices, and that's exactly what happened to Diabolic Revelation.
At first glance, Diabolic Revelation is a rather underwhelming card. The potential to search for multiple cards simultaneously is high, but it requires at least seven mana to be effective. It's no surprise, then, that more efficient tutors, like Diabolic Tutor, see much more play in Commander.
At the same time, however, this hefty sorcery finds a home in decks capable of casting it at a drastically reduced cost. And that's where Witherbloom, the Balancer comes in, making it extremely easy to cast 
spells for a negligible price. Just flood the board with creatures and then search for win conditions like Sprout Swarm and Exsanguinate.
It's no surprise, then, that according to EDHREC, as many as 2,320 decks featuring Witherbloom, the Balancer have already adopted Diabolic Revelation. Even outside of Witherbloom, cards like Rowan, Scion of War offer similar cost-reduction synergies, while Zaxara, the Exemplary perfectly leverages the value of .
The Price Surge
This also had an immediate impact on the European market. On European platforms, at the end of March, Near Mint English copies were easily found between €0.80 and €1. After the emergence of synergies with Witherbloom, the average price rapidly rose to the €8–€10 range, with some sales even reaching €12 for copies in perfect condition. Versions in less sought-after languages or in lower conditions remain slightly more accessible; currently, copies can still be found under €6–€7 on CardTrader, but they will quickly sell out.
The most significant data point is the drastic reduction in stock: many inexpensive listings were absorbed within a few days, leaving only higher-priced copies. This type of dynamic is typical of Commander-driven spikes, where even a single new synergy can quickly deplete an already shallow market, especially for cards with only one printing like Diabolic Revelation.
The trend is also supported by actual adoption in Commander decks: in addition to Witherbloom, the Balancer, Rowan, Scion of War and Zaxara, the Exemplary also contribute to sustained demand, thanks to their ability to leverage spells. This slightly expands the pool of use, making the growth less fragile compared to a purely speculative spike.
Looking ahead, the behavior of the European price will depend on two main factors. On one hand, the sustained popularity of Witherbloom: if the commander continues to be played, Diabolic Revelation is likely to stabilize in the €6–€8 range. On the other hand, potential reprints: being a card with only one printing (Magic 2013), a reprint in a precon or a bonus sheet could quickly bring it back down to €2–€3.
