The HHG skill nerf isn't too bad. It is the rise of many other fast Beatdown decks such as RED-Eye spirit, Hammer-Shark and Naturia that totally 🔥 the Harpies deck.
Like no 🔥ing kidding. At current environments every meta deck can easily summon 2+ high-level beaters with revival options at Turn 1~2. This is simply too much for Harpies deck to handle. Unless more Harpies support cards are introduced in the future I don't see Harpies ever making into meta again.
