Harpies focused on easy swarming, quick deck thinning and flexible Extra Deck options, including the Black Rose to board wipe, Simorgh for protection and even Harmonizer to target troublesome cards in your opponent's GY.
I am still working on what things should go in Side Decks and the ideal number of each card. Suggestions are welcome! Please leave a comment if you have any, or like if you enjoyed it!
