Some choices don't make sense. First: drop Nobleman (you'll rely on field spell effect to destroy the set cards), Riryoku (kind of a dead card), Wild Tornado (if you have another OTC) adn Jerry Beans (afraid of 4-star Ladybug? Then put another Duck).
Second: your deck has little to none defense (Econ, Dollar Wall and Kurboh only). Third: Why this Effect Harpie and not the Hottest one(+300atk)?
Will be very hard to draw a harpie with this deck, add 2 or 3 elegant egotist, add at least one more eliminating the league, take off beans or other beater to add one more WT, remember, in HHG, have good cards means nothing if the enemy get a strong monster and destroy your field spell, you need to be able to trap 🔥 high stats monsters
