[Card] Thalek - Improbable Enemy [Exp.] RD2 [Type] Ref PQ [In-joke] 
The subtitle refers to Thaleks being met through in an alternate universe (with different probabilities) and the idea that they are not enemies in Storm of Angels. The image is based on one of the original Dalek designs by Ray Cusick, so might have been an actual Dalek if things had gone differently (unbound).
