Batch adding a gif to images

[Etan]

New user here, only been using gimp since oct this year. Using it to edit images for trading card bot on discord. Tried doing gif things with it and failed pretty miserably every time. Goal is to add a gif to the card images for a certain rarity. Is it possible to use the batch manipulator to insert the gif as a sort of overlay to the cards (used as a background). 

1. Have gif file that has a transparent back ground
2. card images
3. Use batch to bulk add the gif to multiple card images?


Sorry if i didnt explain it very well. Thanks for your time and help!
