We take a look at each card introduced in the Return To Naxxramas mini-set, Hearthstone's most recent addition to the Standard/Constructed version of the game. This comes as an addition to the March of The Lich King expansion, which added the new Death Knight class and a variety of new hybrid minions.

We've broken this card list down into each class' new cards, as well as the new legendaries & new Diamond cards that have been added as an aesthetic change.
Updated March 4, 2023: We've updated this article to include a video guide that breaks down every card in Return To Naxxramas.
Death Knight Cards
Image
Card
Description
Frost Queen Sindragosa
Legendary Undead Dragon Minion - 7 Cost, 6/6
Colossal +2
After an enemy is Frozen, destroy it.
Sindragosa Wing
Colossal Card - 1 Cost, 2/1
Rush
Freeze any character damage by this minion.
Rimescale Siren
Common Undead Naga Minion, 3 Cost, 1 Frost Rune, 2/3
Battlecry: If you've cast three spells while holding this, Freeze 3 random enemy minions.
Construct Quarter
Rare Location, 3 Cost
Destroy a friendly minion to summon a 4/5 Undead with Rush.
Out of these cards, the only one we can see making its way into the Death Knight meta is Construct Quarter because it synergizes extremely well with the class hero power. Unfortunately, Frost Death Knight is already not an overly popular deck in the meta, and Sindragosa and Rimescale are not powerful enough cards to shift this.
Druid Cards

Card
Description
Life From Death
Rare Nature Spell, 6 Cost
Draw 3 cards
Infuse (6): This costs (1).
Rake
Rare 1 Cost Spell
Give your hero +2 Attack this turn. Deal damage equal to your hero's Attack to a minion.
Death Beetle
Common Undead Beast Minion, 6 Cost, 6/6
Taunt
Manathirst (11): Gain +4/+4 and Charge.
There are some interesting Druid cards here: Death Beetle seems to fit perfectly into big Druid by providing yet another game-ending threat, although this does require you to line up your mana turns with the card. Life From Death is a great card if you manage to get it in your first hand, because drawing 3 cards for the cost of 1 mana is unreal.
Demon Hunter Cards
Image
Card
Description
Felscale Evoker
Rare Demon Naga, 6 Cost, 5/7
Battlecry: If you've cast three spells while holding this, summon a different Demon from your deck.
Calamity's Grasp
Rare Weapon, 1 Cost
Deathrattle: Add a random Outcast card to your hand.
Shambling Chow
Common Undead, 1 Cost, 2/3
Rush
Deathrattle: Deal 4 damage to your hero.
Some pretty straightforward cards here. We like Calamity's Grasp for its random Outcast card, and we reckon that will perform very well in Arena...will it impact the Demon Hunter meta? Probably not, but it's a fun card nonetheless. Shambling Chow is a pretty regular card that might see some play in face Demon Hunter decks, and we don't see Felscale Evoker having much use.

Hunter

Card
Description
Fathful Companions
7 Cost Spell
Discover a Beast from your deck and summon it.
Manathirst (10): Also summon a copy of it.
Trinket Tracker
Common Undead, 1 cost, 1/1
Battlecry: Draw a 1-cost spell.
ZOMBEEEEES!!!
2 Cost Secret
After your opponent plays a minion, summon four 1/1 Zombees to attack it.
Out of these, we like Trinket Tracker as a cheap way to set up some early game plays by drawing the spells you need to get started. Faithful Companions is something you probably want to play on turn 10, and then it can be pretty powerful by playing two massive Beasts. Zombees is a good secret for control Hunter and for face Hunter.
Mage
Image
Card
Description
Whirlweaver
Rare Elemental Naga Minion, 3 Cost, 4/3
Battlecry: If you've cast a spell last turn, Discover an Elemental.
Spectral Trainee
Rare Undead Minion, 3 cost, 1/4
After you cast a spell, deal 1 damage to all enemy minions.
Tear Reality
Common Arcane Spell, 4 Cost
Add 2 random Mage spells from the past to your hand. They cost (2) less.
Both Tear Reality and Whirlweaver are fine cards because they generate new cards, but both have pretty awful cost to value ratio. The stats on Whirlweaver make it not so great, but it might be popular in Arena because Discover is really good at the moment.
Priest
Image
Card
Description
Cannibalize
Rare Shadow Spell, 4 Cost
Destroy a minion. Restore its Health to all friendly characters.
Mind Sear
Common Shadow Spell, 1 Cost
Deal 2 damage to a minion. If it dies, deal 3 damage to the enemy hero.
Rotting Necromancer
Common Undead Minion, 4 Cost, 5/4
Battlecry:Dredge. If it's an Undead, deal 5 damage to the enemy hero.
Undead Priest might get a boost with Rotting Necromancer, whereas we're not sure how Cannibalize and Mind Sear fit into the meta right now. Some sort of control Priest might get some use out of these cards & helping you to stay alive longer.

Paladin

Card
Description
The Purator
Legendary Minion, 5 Cost, 4/6
Taunt
Battlecry: If your deck has no Neutral cards, draw a minion of each minion type.
Goldwing
Rare Mech Dragon Minion, 4 Cost, 3/5
Rush
Battlecry: If you're holding a Mech, gain Windfury.
Knight of the Dead
Common Undead Minion, 3 Cost, 5/5
Battlecry: Deal 5 damage to your hero.
Manathirst (7): Restore 5 health your hero instead.
We can see there being some pretty fun deck archetypes that use The Purator to their advantage, even if they're not classically powerful. As for Knight Of The Dead, this is a high-tempo card that has pay-offs later in the game. We really like the flexibility that the new Manathirst mechanic brings to cards like this.
Rogue

Card
Description
Stitched Creation
Rare Undead Minion, 3 Cost, 1/1
Combo: Gain +2/+2.
Infuse (2): Gain +3/+3.
Manathirst (8): Gain +4/+4
Jolly Roger
Common Undead Pirate, 1 Cost, 1/3
After your hero attacks, summon a 1/1 Undead Pirate.
Ransack
Common Spell, 0 Cost
Deal 1 damage to a minion. If you've played a card from another class this turn, deal 4 instead.
Stitched Creation is one of our favorite cards from this entire set, mostly because it really demonstrates the flexibility of the fun mechanics like Combo, Infuse, and Manathirst. Having this flexiblity throughout the game to play this card with a variety of different power levels is an interesting step for Hearthstone, and one we hope to see repeated in the future.
Shaman
Image
Card
Description
Cold Storage
Rare Frost Spell, 1 Cost
Freeze a minion. Add a copy of it to your hand.
Frostfin Chomper
Rare Elemental Murloc, 3 Cost, 2/3
Battlecry: If you played an Elemental last turn, summon three 1/1 Murlocs.
Blazing Transmutation
Common Fire Spell, 1 Cost
Choose a minion. Discover one that costs (1) more to transform it into.
Murlocs! Got to love Murlocs. However, it's really Cold Storage that has caught our attention out of these new Shaman cards. You can Freeze an enemy minion to yoink it, or use it to stack more minions on your side of the board. Another interesting and flexible card that could see some play, considering it's so cheap.

Warrior

Card
Description
Training Session
Spell, 1 Cost
Discover a Taunt minion. If you play it this turn, repeat this.
Hookfist-3000
Common Mech Pirate Minion, 3 Cost, 4/3
After your hero attacks, gain 4 Armor and draw a card.
Fleshshaper
Common Undead Minion, 6 Cost, 3/8
Taunt
Battlecry: If you have 5 or more Armor, summon a copy of this.
Training Sessions is a great card, because you've got the flexibility to fill your board with multiple low-cost Taunt minions, or play a massive Taunt minion depending on your situation. This is great for Arena, but we're not sure what deck exactly this will fit into for Constructed.
Warlock
Image
Card
Description
Suspicious Peddler
Rare Undead Minion, 2 Cost, 2/3
Battlecry: Discover a 1-Cost card. If your opponent guesses your choice, they get a copy.
Nofin's Imp-ossible
Rare Spell, 2 Cost
Give all friendly Demons and Murlocs "Deathrattle: Summon a 2/2 Imploc."
Plague Eruption
Common Spell, 3 Cost
Deal 2 damage to all minions. If you've discarded a card this game, deal 1 more.
Nofin's Impossible is the stand-out card from this small selection of Warlock cards. More Murlocs, more good - that's what we say, sometimes. Zoolock is a classic Hearthstone deck, and we think this card could see some play there.
Neutral
Image
Card
Description
Rivendare, Warrider
Legendary Undead Minion, 6 Cost, 6/6
Deathrattle: Shuffle the other 3 Horsemen into your deck.
Blaumeaux, Faminerider
Legendary Undead Minion, 6 Cost
Lifesteal
Deathrattle: If you had all four Horsemen die this game, destroy the enemy hero.
Korth'azz, Deathrider
Legendary Undead Minion, 6 Cost
Rush
Deathrattle: If you had all four Horsemen die this game, destroy the enemy hero.
Zeliek, Conquestrider
Legendary Undead Minion, 6 Cost
Taunt
Deathrattle: If you had all four Horsemen die this game, destroy the enemy hero.
Thaddius, Monstrosity
Legendary Undead Minion, 10 Cost
Taunt
Your odd-Cost cards cost (1). (Swaps polarity each turn!)
Mistake
Rare All Minion, 1 Cost, 1/3
This has all minion types.
Darkfallen Shadow
Common Undead Minion, 3 Cost, 3/3
Rush
Manathirst (6): Gain Reborn.
Lost Exarch
Rare Undead Minion, 4 Cost, 5/4
Deathrattle: Spend all your Mana. Summon that many 2/2 Zombies with Rush.
Some more really fascinating cards from the Neutral selection, including the Rivendare horsemen - it's a bit of a gimmick, and is probably way too slow to actually see any play at all, but we do love the idea of pulling this game-ending combination off. Out of these, we've got to go with Mistake as our favorite card, because it's simple and fits into loads of decks and archetypes.
