Yugioh Deck help for Regionals?

nice deck ... best advanced format legal harpie deck i have seen ... how about putting a terraforming in? ... another suggestion i have is flying kamakiri #1 ... this will let you special summon your harpie lady 1 (although this is the only card i can see to use this for atm) ... or your could use it as a tribute for raiza/swift birdman joe ... cant really help much since i dont use harpies but hope this helps
