Cards are duplicated in spoiler files when there are several pictures available

[tooomm]

Our script creates a new card with identical values, expect a different picture URL.

See example in current deployment:

<card> 
   <name>Tezzeret, Betrayer of Flesh</name> 
   <text>The first activated ability of an artifact you activate each turn costs {2} less to activate.+1: Draw two cards. Then discard two cards unless you discard an artifact card.−2: Target artifact becomes an artifact creature. If it isn't a Vehicle, it has base power and toughness 4/4.−6: You get an emblem with "Whenever an artifact you control becomes tapped, draw a card."</text> 
   <prop> 
     <color>U</color> 
     <type>Legendary Planeswalker - Tezzeret</type> 
     <cmc>4.0</cmc>

In the above example, two of those pictures are even the same (not the same link though).

Just realized that this happened with other sets before and is not a new issue: #269
