1. Go to Mage Repository
2. Run command exemplified below:

For cards added since tagOrSha1 till head revision (you can replace HEAD with another tagOrSha1):
git log tagOrSha1..HEAD --diff-filter=A --name-status | sed -ne 's/^A[^u]Mage.Sets\/src\/mage\/sets\///p' | sort -u > added_cards.txt

for Windows: you need to replace ' by "" and remove -u in sort

Example for cards implemented from 0.8.7 till 0.9:
