This is a run of the Challenge mode, playing as Yugi. Difficulty was Easy; done on New Game Mode. Falsebound Kingdom also has the New Game + version of Challenge Mode unlocked once Joey Story is completed, which would likely be even faster as you can Raigeki through opponents.

Overall, I liked that run. Did have a miss or two, but otherwise

Setup was Yugi as a marshall with all Harpie Ladies. Each Harpie having the following equips: -Beast Fangs -Cyber Shield -Electro-Whip

Beast Fangs and Cyber Shield for added attack power; Electro-Whip to allow cut down on enemy turns with paralysis. Selected Yugi as he's what I would call the closest to being compatible with the Harpies by Marshall colour, though I could be wrong there.
