I noticed a few oddities in the 5WD cards while going through them, so I decided to brave the xml a bit:
Werewolf Hunter [R15],
Tormenting Voice [R15],
Niricon Skirmisher [ONE],
Demoncult Idol [ARH],
Coltrorr Charm [5WD],
Channel the Maws [5WD], and
Aldair Eamon, Scion of the Seal [COS] are in the xml twice as duplicate entries of the same set.
Sparksigil Apprentice [STS, VLT],
Pacifism [TAR, UND]
Oakenform [SGT, BLI/R15], and
Meditation [NM3, CAT] are in the xml twice as part of different sets.
There are two different cards named
Waterwhelm, in ASC and in VKC.
There are two different cards named
Voice of Unity, in STS and CAT.
Rampaging Slagkite is listed as common, should be rare.
Null Echoes from 5WD is missing from the xml:
Code:
<card>
<name>Null Echoes</name>
<set rarity="R">5WD</set>
<color>R</color>
<manacost>1RR</manacost>
<cmc>3</cmc>
<type>Instant</type>
<tablerow>3</tablerow>
<text>Copy target instant or sorcery spell. You may choose new targets for it.
Mergeback — {3}{R}{R}, Put Null Echoes from your graveyard on the bottom of your library: Copy target instant or sorcery spell, or triggered or activated ability. You may choose new targets for that spell or ability.</text>
</card>
There are two different cards named
Mysterious Disappearance, in COV and VEL.
Morasol Flies is a Creature - Instant, should probably be Creature - Insect.
There appears to be an errant "ee" after the color tags in the entry of
Intrepid Messenger.
There are two different cards named
Hoard, in BST and ENT.
There are two different cards named
Fill the Grave in NM3. The aura should be Licence to Kill [NM3] due to
License to Kill [COV].
There are two different cards named
Edict of Solitude, in VER and VLT. The VER one also missed Enchant creature
Drifting Meadow [POP] is missing rarity data (common).
Cauldron Dweller [WOM] has its rarity data in the color tag rather than the set tag.
Autograph Elemental [NM3] is misnamed
Aether Transmuter.
