There are now 2 cards named Death Coil (The Warlock version and the Death Knight version).

Currently, if you view the Death Coil from the Death Knight Starter set, it will show the Warlock tooltip.

Maybe use the set name to identify which version it is?

Yep, I knew about it when I imported the cards but then when I implemented the tooltips and the new card links I forgot :D

I changed it so that now the warlock one is called [wow]Death Coil[/wow] and the death knight one is called [wow]Death Coil (Death Knight)[/wow]. The bug is gone, and now it's much clearer also when you use autocompleted inputs (like Quick add).

Awesome, thanks =)
