Honestly, what the hell does Endeavor(as a word) have anything to do with Endeavor(as a move). If maybe the word etymology came up I'd understand it better. For example
Leaf-one of the expanded, usually green organs borne by the stem of a plant.
Blade-the flat cutting part of a sword, knife, etc
= An attack that has a flat, sharp leaf, that is used as a blade to attack
Simple yet effective, I think it just might work
