Synopsis :
Harpie's are an older deck that have been revamped through Xyz monsters and new support. Controlling the field by destroying opponents backrow and having hard removal to other cards your opponents control, Harpie's are also capable of being aggressive and consistent.
Key/ Notable Cards :
Harpie Channeler WIND
4 Stars
1400/ 1300 -- Winged-Beast/ Effect
You can discard 1 "Harpie" card, except "Harpie's Brother"; Special Summon 1 "Harpie" monster from your Deck, except "Harpie Channeler" or "Harpie's Brother". You can only use this effect of "Harpie Channeler" once per turn. If you control a Dragon-Type monster, this card's Level becomes 7. This card's name is treated as "Harpie Lady" while it is on the field or in the Graveyard.
Harpie's Pet Dragon WIND
7 Stars
2000/ 2500 -- Dragon/ Effect
This card gains 300 ATK and DEF for each "Harpie Lady" on the field.
Summoner Monk DARK
4 Stars
800/ 1600 -- Spellcaster/ Effect
Cannot be Tributed. When this card is Normal or Flip Summoned: Change this card to Defense Position. Once per turn: You can discard 1 Spell Card; Special Summon 1 Level 4 monster from your Deck, but that monster cannot attack this turn.
Harpie Channeler is a great card to initiate combos, being similar to Summoner Monk in regards to the hand cost and the appropriate targets, save for Harpie's Pet Dragon, which can be used for Number 11: Big Eyes to create OTKs, disrupt next turn combos, or maintain general field control. The card itself is pretty self-explainable, but being a target for Summoner Monk, which it closely relates to, being a medium for Elegant Egotist, and being the specific, required material for other powerful Xyz monsters.
Harpie's Hunting Ground
Field Spell
When "Harpie Lady" or "Harpie Lady Sisters" is Normal Summoned or Special Summoned, destroy 1 Spell or Trap Card on the field. All face-up Winged Beast-Type monsters gain 200 ATK and DEF.
Harpie Queen WIND
Level 4
1900/ 1200 -- Winged-Beast/ Effect
You can discard this card to the Graveyard to add 1 "Harpies' Hunting Ground" from your Deck to your hand. This card's name is treated as "Harpie Lady" while it is on the field or in the Graveyard.
Although Hunting Ground is particularly effective against Mermail/ Atlantean decks, or any monster-based engine deck that doesn't require traps, a 200 boost for a Harpie Queen means the difference between suiciding into Thunderking Rai-Oh and other big level 4 monsters (and a few Xyz monsters). More importantly, against decks that do utilize a lot of traps and spells, Hunting Ground is a forced monster negation to save a vital spell or trap, or facing Harpie Channeler, a backrow pop, a summon, another backrow pop, followed up by an Xyz because they didn't choose to negate your summon, or couldn't. Queen not only initiates these kinds of plusses from a single summon by searching, but is also indirect removal for other cards through Hunting Ground, and through attacking. Queen, like every other Harpie monster in the deck, fulfills the requirements for some needed Xyz monsters that most other decks can't utilize.
Elegant Egotist
Spell
Activate only while there is a face-up "Harpie Lady" on the field. Special Summon 1 "Harpie Lady" or "Harpie Lady Sisters" from your hand or your Deck.
Hysteric Party
Continuous Trap
Discard 1 card from your hand. Special Summon as many "Harpie Lady" cards as possible from your Graveyard. When this card is removed from the field, destroy all the monsters that were Special Summoned by this card's effect.
Hysteric Sign
Continuous Spell
When this card resolves: Add 1 "Elegant Egotist" from your Deck or Graveyard to your hand. During the End Phase, if this card in your hand or on your side of the field was destroyed and sent to the Graveyard this turn: Add 3 "Harpie" cards with different names from your Deck to your hand, except "Harpie's Brother". You can only activate the effect of "Hysteric Sign" once per turn.
Both of these cards are prime choices for extending plays by overlaying into Xyz monsters. Because Elegant Egotist is searchable via Hysteric Sign, a single copy is sufficient for most matches, unless you want to go into Shock Master immediately for decks like Mermails/ Atlanteans, Fire Fist, Hieratics, Prophecy, ect. Any deck would beg for an equivalent of Elegant Egotist, so having access to its searchability and recyclability are highly relevant in mid to late game plays. Hysteric Party works in the same fashion. Although not typically good early game due to lack of Harpie monsters in your graveyard, it's a good card to topdeck into if neither player has significant advantage, and if you have the life to spare for an extra turn. The hand discard cost is similar to Summoner Monk and Harpie Channeler, except not cost specific and more efficient mid and late game due to lack of deck presence for both Summoner Monk and Harpie Channeler. Better than a Monster Reborn if you can spare a card, which 2 Xyz monsters merit. Moreover, the synergy between Sign and Hunting Ground provides cost targets for Harpie Channeler and thinning the deck, making it easier to draw into staple spells, and provides the cost needed to be paid for Hysteric Party, which can also contribute to the monsters summoned through its effect.
Extra Deck :
Lightning Plover WIND
Rank 4 Xyz
1900/ 1600 -- Thunder/ Effect
2 Level 4 WIND monsters
When this card is Xyz Summoned: Target 1 Set card your opponent controls; return it to the bottom of the Deck. Once per turn: You can detach 1 Xyz Material from this card to target 1 face-up card your opponent controls; return it to the top of the Deck.
Likely being summoned after two backrow pops from Hunting Ground, Plover can get rid of any other card on the field. Once when being summoned, targeting a set card, and again as an ignition effect for any big monsters or Zenmaines. Sweeping their field and retaining a monster with decent attack is game changing, being comparable to Inzektors and Mermails/ Atlanteans.
Terrorfang, Diawolf EARTH
Rank 4 Xyz
2000/ 1200 -- Beast/ Effect
2 Level 4 monsters
Once per turn: You can detach 1 Xyz Material from this card to target 1 Beast, Beast-Warrior, or Winged Beast-Type monster you control and 1 other card on the field; destroy them.
Scrap Dragon for a few decks, including Harpies. Although not typically as viable as Lightning Plover, it's a nice way to get rid of field presence. Not much to be said, being comparable to Scrap Dragon and Lightning Plover; albeit, not as good as either.
Number 11: Big Eye DARK
Rank 7 Xyz
2600/ 2000 -- Spellcaster/ Effect
2 Level 7 monsters
Once per turn: You can detach 1 Xyz Material from this card to target 1 monster your opponent controls; take control of that monster. This card cannot attack the turn you activate this effect.
As explained earlier, Big Eye disrupts next turn plays, takes field control, and creates OTKs. Easily summoned through Harpie Channeler and Harpie's Pet Dragon, which will pop a backrow card of their, followed by further field control through his effect.
Decklist #1
Spoiler :
A basic Harpie deck. No gimmicks or bad tricks. Some pretty basic plays are,
Step 1. Pitch Harpie's Queen for Harpie's Hunting Ground
Step 2. Play Harpie's Hunting Ground or Summoner Monk. HHG is an optional step throughout this combo depending on how much backrow your opponent has, and if you have Hysteric Sign. You'd want to play HHG before you summon a monster(s) based on the amount of things you want to pop. A few seconds of remembering this will keep you from popping itself.
Step 3. Summoner Monk ef for Harpie's Channeler.
Step 4. Pitch for Harpie's Channeler.
Step 5 (optional). Elegant Egotist for whatever Harpie you want
Final Step. Xyz for whatever monster(s) are most appropriate for your situation.
Step 1. Take Damage and summon Trag.
Step 2. Summon Harpie's Channeler.
Step 3. Harpie's Channeler ef for Harpie's Pet Dragon and change Trag to level 4.
Step 4. Elegant Egotist for Harpie Lady 1.
Step 5. Summon Lightning Plover and remove backrow.
Step 6. Summon Big Eye and take control of monster.
Step 7 (optional). Spin another monster they control.
Final Step. Attack directly.
I'm not going to go too in-depth with all the combos of this deck since the steps for each combo are interchangeable with a step in another combo, depending on your hand. All combos can use any of the above cards in another combo, so you can pretty much do whatever you want as long as you have cards to pitch for Monk or Channeler, which is easy to do given the high spell count, and popping Sign for searches. You can also summon double Mirage Dragon for 4K direct every assuming you can summon the first one, and have Hysteric Party set with enough monsters in your grave. Can also be used for double Shock Master, both of which happen often enough if you play correctly with the right cards.
Decklist #2 -- Black Harpie
Spoiler :
Something like Black Valley. The deck doesn't have very many combos, and none of which are difficult to find, so I won't go into all but one of these combos. That being Xyz into Lavalval Chain and dump for Dark Sim, or dump Dark Sim to discard from your hand to summon. The deck itself focuses on thinning the deck out and drawing through Reckless or using PoD to search for it. Play Anti-Spell Fragrance with Dark Sim on the field and you've created a spell and set lockdown. Objective of the deck is to get the lockdown first, and everything second if you can afford to. Not very much to say about it.
