Honestly, I feel like none of the upgrades in Saber really had any narrative or emotional weight until Primitive Dragon. The three-book combos, Jaou, Dragonic Knight, King Lion, X Swordman, some of them looked good visually but they brought so little to the story that they might as well not exist except to sell toys. Rekka glowing and being able to separate humans from Megid was a more meaningful power-up than most of Touma's books!
