Magic: The Gathering's Innistrad: Crimson Vow is now available in paper form. However, Wizards of the Coast announced Crimson Vow Set Booster product delays for North America and Canada through release. Thus, anyone selling Crimson Vow singles at release likely sourced cards from Prelease Kits, Draft Boosters, or Collector Boosters. 

It's hard to say if Crimson Vow Set product delays are affecting average market prices for singles. Regardless, many of the mythic rares cards are selling for over $10 each. Let's take a look at the top 10 most valuable regular versions of cards heading into Crimson Vow's release date. 

10. Cemetery Prowler 

Cemetery Prowler is a three-mana 3/4 Wolf, and part of the mythic rare cemetery cycle, that lowers the casting cost of your spells that share a type with a card it exiles. Aggressive Standard decks can utilize Cemetery Prowler to reduce the casting cost of creatures like Volatile Arsonist and Ulvenwald Oddity. Cemetery Prowler could be the element that pushes Standard Gruul decks into the top tier of competitive play. 

9. Chandra, Dressed to Kill

Chandra, Dressed to Kill is a three-mana Planeswalker with an average market price over $10, and its borderless artwork is a genuine showstopper. Sparks will fly as Chandra possesses two +1 abilities that generate additional mana and card advantage. Her -7 should be able to end a game in a burn-centric Standard deck. If Mono-Red makes a comeback in Standard, we can expect to see Chandra in it. 

8. Cemetery Gatekeeper

Cemetery Gatekeeper is an aggressive two-mana Vampire with an average market price of over $10. Since Cemetery Gatekeeper's ability deals two damage periodically to players, it may be a better fit in Standard Red Aggro over Rakdos Vampires. Vampire decks have other two-mana creature options such as Bloodtithe Harvester and Vampire Socialite. Keep in mind that Cemetery Gatekeeper's ability can damage any player, including yourself.   

7. Hullbreaker Horror

Hullbreaker Horror is the only rare to breach the top 10 most valuable cards in Crimson Vow. The stats on Hullbreaker Horror, along with its outstanding abilities, may cause your opponents to tremble in fear — it's eben making waves in Standard as a new inclusion in Izzet Control decks. In Commander, Hullbreaker Horror is an incredible addition to sea monster decks led by Aesi, Tyrant of Gyre Strait, Arixmethes, Slumbering Isle, and Runo Stromkirk.

6. Sorin the Mirthless

If you are a fan of Bob, AKA Dark Confidant, Sorin the Mirthless is a card you should not overlook. Sorin's +1 mimics Dark Confidant's ability, and his -2 produces Vampire Nighthawk without deathtouch. Rakdos Vampires is an ideal home for Sorin the Mirthless in Standard. The average market price for Sorin the Mirthless may be under $15, but the showcase version with artwork by Ayami Kojima is over $30! 

5. Toxrill, the Corrosive

Toxrill, the Corrosive is a black 7/7 Slug Horror that may turn the tide of battle in your favor. With an average market price over $10, Toxrill is officially the most expensive Slug in MTG. Standard Control and black Commander decks may want Toxrill to eradicate opponents' creatures and build an army of black 1/1 Slug creature tokens. With any luck, WotC will introduce more Slug cards in the future that synergize with Toxrill.

4. Manaform Hellkite

Crimson Vow blessed players with another red mythic rare Dragon in Standard. At first glance, Manaform Hellkite appears to be the next Shark Typhoon. However, X/X red Dragon Illusion creature tokens with flying and haste created by Manaform Hellkite get exiled at the beginning of the next end step. Whether you cast Spikefield Hazard or Alrund's Epiphany, Manaform Hellkite produces creature tokens that can pressure an opponent's life total. Whether Goldspan Dragon will get overthrown by Manaform Hellkite remains to be seen.

3. Avabruck Caretaker

Avabruck Caretaker is a green mythic rare Werewolf with an average market price under $15. It's also notably the only Werewolf in Crimson Vow's top 10 most valuable cards. Tovolar, Dire Overlord Commander decks probably want to include Avabruck Caretaker as a win condition. The playability of Avabruck Caretaker outside of Commander remains unclear, but there is hope for it in Standard Gruul Werewolves.

2. Cultivator Colossus

Cultivator Colossus is Crimson Vow's second most valuable card, with an average market price of over $15. The allure of Cultivator Colossus is its size and ability, particularly in Commander. Cultivator Colossus may see immediate play in land-centric decks helmed by commanders like Obuun, Mul Daya Ancestor, Tatyova, Benthic Druid, and Lord Windgrace.

Cultivator Colossus is a two-card combo with Abundance, which saw a reprint last year in the Land's Wrath Commander precon deck. Abundance replaces the draw effect of Cultivator Colossus' ability, enabling you to place all remaining lands in your library on the battlefield tapped. Your opponents will need to answer a 30+/30+ trampling Plant Beast, as well as anything you may cast next turn with a plethora of mana available. 

1. Necroduality

The top spot for the highest value card in Crimson Vow belongs to Necroduality. Historically, enchantments that create copies of creatures entering the battlefield are powerful (and expensive) additions to Commander decks. Doubling Season, Parallel Lives, and Anointed Procession are other four-mana enchantments offering similar effects for tokens. 

Gravecrawler" || "Phyrexian Altar

One of Necroduality's benefits is its ability to copy Zombies entering the battlefield from the graveyard. Pairing Gravecrawler and Phyrexian Altar with Necroduality can create infinite Gravecrawler creature tokens and mana. Necroduality synergizes well with Noxious Ghoul to ensure that only Zombies remain on the battlefield. It's no surprise that Necroduality has become the most expensive card in Crimson Vow.
