Greenbot (Event Pack 2024 Vol. 2)

[LV1][LV2] During Opponent's Turn

If this spirit has a (soul core) on it, when one of your white or green non-token spirits is destroyed by your opponent, you may summon one of your Mecha Leaf Kindred Tokens (Token spirit/[White/Green]/0 Cost/Mecha • Leaf Kindred • Token/LV1(1)/BP2000/). (Token cards come from outside of the
game. Place cores onto them from either your field or your reserve.)
