Harpie Decks...these are around the level of Amazoness in terms of greatness, but I'd rank them a little lower. ROD brought about some nice Harpie support; Harpie's Hunting Ground, Harpy Lady 1/2/3, and Triange Ecstasy Spark all help support this theme.
The three new Harpies are all good in their own accord; most people prefer 1 over 2 and 3, and I'd have to agree. I personally find 3 to be a waste, while others find 2 to be a waste. Unfortunately, you can't side-deck any number of them, because they all count as "Harpy Lady." Because of this, I'm going to maindeck one of each, but feel free to play around with this number as you which. I personally suggest two Harpy Lady 1 and one Harpy Lady 2, totally leaving Harpy Lady 3 out of the deck.
Harpie Lady Sisters can ONLY be Special Summoned through Elegant Egotist, and NOTHING else. That still means that you can normaal summon them, however. Sisters gets some support with Triangle Spark, however since Sisters in itself is situational, only one Spark should go in. Pet Dragon shouldn't be used; it simply isn't worth it.
Harpie's Hunting Ground, while very nice, isn't that great of a card. Most people like two HL 1 and one HL 2, so the boost is already there. Hunting Ground also FORCES you to destroy a m/t on the field, so if the opponent has a clear m/t zone, you have to destroy something of your own. Not fun.
