I'm trying to finish off my Serenity master set, but I'm having a hard time getting hold of the action figure promos. Does anyone have any info on these - which cards came with which figures, etc..

Thanks in advance

Not sure how many there are in total but I have three in my collection. DS S1 features same picture as SP WW promo card and came with Malcolm Reynolds figure, DS S3 features River & a Reaver and came in Reaver figure and DS S4 features Jayne and came in the common Jayne figure. There is a variant Jayne figure but I dont know if the card is different All the cards are foils.

DSS1 Malcolm (Inserted in with the Malcolm "Mal" Reynolds figure)
DSS2 Fight to the Finish (Inserted in with the Final Battle "Mal" figure)
DSS3 Reavers Attack (Inserted in with the Reaver figure)
DSS4 Soldier of Fortune (Inserted in with the Jayne figure)
DSS5 Jayne (Inserted in with the Mercenary Jayne figure)

All of which I am also looking for.

Since I'm an action figure collector also I have all 5, they are very nice cards. You can pick the figures up quite cheap off eBay.
