Dungeons & Dragons: Adventures in the Forgotten Realms became available in paper form on July 23rd. Tiamat and Old Gnawbone had the highest average market prices heading into release day among all the cards in the set. Both cards saw prices hovering around $20 for regular versions, with Tiamat edging out Old Gnawbone by less than $1.

Throughout the Forgotten Realms release weekend, average market prices fluctuated for many in-demand cards. Most Standard cards typically fall in price coming out of presale. However, a few Forgotten Realms cards maintained or even increased in price between Friday, July 23rd, and Sunday, July 25th. Let's look at the 10 most valuable regular versions of cards in Forgotten Realms following its paper release.

#10: Treasure Vault

Treasure Vault technically fell out of the top 10 most valuable cards list after release weekend because Ebondeath, Dracolich regular version average market price is higher by a few cents. However, Treasure Vault's product-hover id="243495" is more valuable than the regular version of Ebondeath, Dracolich. Since Treasure Vault was the 10th most valuable card before and after release weekend, it remains on this list.

A key benefit of Treasure Vault is its artifact land typing. Cards that care about artifacts can take advantage of Treasure Vault's typing and zero mana cost (since it's a land). There are less than 20 non-basic artifact lands in Magic: The Gathering, including 10 from Modern Horizons 2. Artifact lands from Mirrodin got banned in Modern due to their strong synergy with Affinity decks.

Beyond Treasure Vault typing, it enters the battlefield untapped and produces colorless mana. If you need more artifacts or mana ramp, you may pay XX and sacrifice Treasure Vault to create X Treasure tokens. In Commander, Treasure Vault pairs well with Oswald Fiddlebender, Prosper, Tome-Bound, and Kalain, Reclusive Painter. Outside of Commander, Treasure Vault is in a Standard Azorius Artifacts deck.

#9: Xanathar, Guild Kingpin

Xanathar, Guild Kingpin is an interesting commander choice for about $9. Xanathar's ability allows you to play cards off the top of an opponent's library during your turn, including lands and spells. In addition, Xanathar locks the chosen opponent out of casting spells for your entire turn. 

Pairing Xanathar, Guild Kingpin with Paradox Haze enables you to target two opponents each turn. Copying Xanathar with Sakashima of a Thousand Faces also allows you the opportunity to target multiple opponents. While you may not be able to play more than one land each turn, you do get to cast spells off the top of each opponent's library.

#8: Circle of Dreams Druid

Edging out Xanathar, Guild Kingpin for the 8th spot is Circle of Dreams Druid. Putting Gaea's Cradle on a creature is very appealing. Standard and Pioneer Elves decks may want some number of Circle of Dreams Druid. However, Circle of Dreams Druid's casting cost limits its playability outside of mono-green decks.

In Commander, Circle of Dreams Druid is a shoo-in for Ezuri, Renegade Leader and Lathril, Blade of the Elves. Both commanders are focused on amassing an army of Elves on the battlefield. Other Elf commanders will want to consider including Circle of Dreams Druid as well.

#7: Iymrith, Desert Doom 

For five mana, Iymrith, Desert Doom is a Dragon with excellent stats for under $10. Iymrith, Desert Doom is a 5/5 Dragon with flying, pseudo-ward, and a card draw ability. Also, Iymrith, Desert Doom shares many similarities with the former Standard all-star Dragonlord Ojutai. If you are interested in a top-end blue finisher for a Standard deck, look no further than Iymrith, Desert Doom.

Standard Izzet Dragons decks are incorporating Iymrith, Desert Doom alongside Goldspan Dragon and Galazeth Prismari. Post-rotation, it is probable that Izzet Dragons will become a top-tier deck in Standard. If Standard is not your forte, you may consider adding Iymrith, Desert Doom to a handful of Dragon Commander decks, including Tiamat and The Ur-Dragon.  

#6: The Book of Exalted Deeds 

Coming in 6th is The Book of Exalted Deeds with an average market price of $10. The Book of Exalted Deeds' activated ability enables you to turn an Angel into a Platinum Angel, preventing you from losing the game and your opponents from winning the game. You may be aware that The Book of Exalted Deeds was recently banned in Standard 2022 on MTG Arena due to its combo with Faceless Haven. Since Standard 2022 is a Best-of-One format, opponents were unlikely to have a way to destroy a nonbasic land with an enlightened counter.  

The Book of Exalted Deeds and Faceless Haven combo is seeing play in Mono-White Aggro decks in the current Standard format. Search for Glory makes it easier to assemble the combo since it can find either The Book of Exalted Deeds or Faceless Haven. Beyond Standard, The Book of Exalted Deeds is in Pioneer decks, including Selesnya Angels and Azorius Book. Mutavault replaces Faceless Haven in Pioneer decks since its activated ability is less taxing on mana requirements.

#5: Lolth, Spider Queen

Lolth, Spider Queen has an average market price of slightly over $10. Note that Lolth does not have a +1 loyalty ability. Instead, Lolth's passive ability adds a loyalty counter each time a creature you control dies. Using the -3 ability adds two 2/1 black Spider create tokens with menace and reach that can block, attack, and add loyalty counters to Lolth.

If Lolth, Spider Queen is running low on loyalty counters, the +0 ability is an acceptable option to draw cards. Lolth synergizes well with sacrifice decks, especially those including Plumb the Forbidden. Currently, Lolth is an inclusion in the Standard Abzan Blink deck.

#4: Inferno of the Star Mounts 

Inferno of the Star Mounts is one of the most powerful creatures in Forgotten Realms. With an average market price of about $12, Inferno of the Star Mounts can quickly end a Standard or Commander game. Not only is Inferno of the Star Mounts uncounterable, but it also has an activated ability with the potential to deal 20 damage to any target.

Standard players are trying Inferno of the Star Mounts in some Grixis and Izzet Dragons decks. Inferno of the Star Mounts may have a hard time knocking off Goldspan Dragon as the ideal top-end for a Standard Dragon deck, but it does show potential in Commander. Tiamat, The Ur-Dragon, and Lathliss, Dragon Queen may want Inferno of the Star Mounts in their 99. Also, Dragonborn Champion is a new Commander staple that could benefit from Inferno of the Star Mounts.

#3: Demilich

Demilich is the 3rd most valuable Forgotten Realms card, with an average market price of around $15. During spoiler season, Demilich received considerable attention due to its unique and powerful abilities. While the mana cost of Demilich appears to be an obstacle, casting four instant or sorcery spells in one turn reduces the casting cost to zero.

Players are including Demilich in Izzet decks across MTG formats. At the moment, Modern Izzet Phoenix is probably the best shell for Demilich. The deck synergizes with Demilich by pitching cards to the graveyard and casting multiple spells in one turn. Faithless Salvaging is a relatively new inclusion for Izzet Phoenix that complements Demilich by filling the graveyard and drawing cards, and it can be cast for free with rebound.

#2: Tiamat

The Legendary Dragon God Tiamat has an average market price of $20. Fans of Dungeons & Dragons are excited to see Tiamat as one of the mythic rares in Forgotten Realms. Tiamat's five-color casting cost reflects the colors of its five heads. In addition to being a 7/7 Dragon God with flying, Tiamat allows you to search your library for up to five Dragons not named Tiamat with different names and put them into your hand, as long as you cast it.

Tiamat is an excellent five-color Dragon tribal commander. Additionally, players electing to use The Ur-Dragon as their Dragon tribal commander could include Tiamat in the 99.

#1: Old Gnawbone

With an average market price over $22, Old Gnawbone surpassed Tiamat as the most valuable card in Forgotten Realms. Old Gnawbone is an exciting Commander card with the ability to create Treasure tokens equal to the combat damage your creatures deal to opponents. A prominent home for Old Gnawbone is in Dragon Commander decks helmed by Tiamat or The Ur-Dragon. Old Gnawbone also synergizes with other notable Commander strategies including creature tokens, Gruul Aggro, and Treasure.

Chatterfang, Squirrel General or Rhys the Redeemed could include Old Gnawbone to enable each creature token you own on the battlefield the chance to generate Treasure through combat. Gruul decks might want to pair Old Gnawbone with Xenagos, God of Revels or Proud Wildbonder. Lastly, Korvold, Fae-Cursed King could use Old Gnawbone's ability for Treasure shenanigans with Dockside Extortionist and Revel in Riches.
