Harpie Cards/Support

[Dramatic Crossroad]

Backstory: I've been playing a lot of Master Duel until recently and I really enjoy winged beast and wind monsters.
So Harpies were and still are my 1st choice, although they've fallen out of Konami's radar.
Goal: Create relevant support with the least amount of cards. (+yes, I know of the new Pet Dragon OCG exclusive, but i feel they need a bit more).

1. Fix the issue with the "Harpie Lady Sisters" brick and the new "Level 5 or higher" boosted effect requirements.

Harpie Sisters (WIND)
Level 4 
[ Winged Beast / Effect ]
(This card's name is always treated as "Harpie Lady Sisters".)
If you control no monsters; You can Special Summon this card (from your hand) as a Level 5 monster.
If this Normal Summoned card attacks your opponent's Special Summoned monster; You can return both to the hand at the start of the Damage Step.
ATK/1450 DEF/1600

Logic:  Its varied level makes it a valid Synchro/Xyz Material and searchable with H.Harpist, while being a good combo starter/comeback piece to use with Oracle/Perfumer/Feather Rest. The other effect is basically a more heavily restricted & more vulnerable version of "Grand Mole", for when you're in a real pinch and your opponent has destruction/targeting immunity. Will work with "Harpie Lady Elegance" and "Triangle Esctasy Spark" (if you wish to actually use) will almost double its ATK and make it a "Jinzo" for a turn.

2. Make "Harpie Lady" shine as the cornerstone of the archetype as toolbox/combo piece.

Harpie Diva (WIND)
Level 4 
[ Winged Beast / Effect ]
(This card's name is always treated as "Harpie Lady".)
If this card is Summoned: You can return 1 "Harpie" monster you control to your hand; Special Summon 1 "Harpie" monster from your hand with a different original name from the monster returned. You can activate the effect of a card with the original (printed) card name "Harpie Diva" only once per turn.
ATK/1300 DEF/1400

Logic: Now, instead of just being a body on the field to use as material for Extra Deck summons, Harpie Lady can extend your "Elegant Egotist" plays even further. You can bounce off H. Oracle/Perfumer/Channeler to reuse on your next turn and maintain hand advantage without losing field presence. Designed to work its magic with H.Conductor & Divine Wind of the Mist Valley.

3. Additional Ideas - even more tools for various situations

Harpie Trio (WIND)
Level 5
[Winged Beast / Fusion / Effect ] 
"Harpie Lady" + "Harpie Lady Sisters"
This card's name becomes "Harpie Lady Sisters" while on the field and in the GY.
You can Special Summon this card (from your Extra Deck) by shuffling 1 "Harpie Lady" from each your hand, GY and side of the field into the Deck. (You do not use "Polymerization".).
You can Summon "Harpie Trio" only once per turn.
ATK/1650 DEF/1800

Logic: Alternative way to place "Sisters" on the field if you can't trigger the conditions for the main deck version. Can be brought out even if you ran out of Summons (but still requires the original "Harpie Lady" in your hand, because only it has that name while in the hand). It's designed to work with "Instant Fusion" and "Fusion Deployment". Still has lower stats than the original HLS to not outshine it completely.


A mini-storyline. 

Harpie's Pet Dragon Hatchling (WIND)
Level 1
[Dragon / Tuner / Effect ]
Once per turn: You can target 1 "Harpie" monster you control that has a Level; This card's Level becomes the same as the target's until the End Phase, but any non-WIND monsters you Summon from the Extra Deck cannot activate their effect(s) and have their effects negated until the End Phase.
ATK/ 200 DEF/250

(The card depicts a Dragon Hatchling, on which Harpie Channeler is putting a chained collar, while Harpie's Pet Dragon seems distraught in the background).

Ex-Pet Enraged Dragon (WIND)
Rank 7
[Dragon / Xyz / Effect ]
2 Level 7 WIND Dragon monsters
Must be Special Summoned by destroying the above monsters you control and cannot be Summoned by other ways. This card is unaffected by other cards and effects while you control a "Harpie Lady" monster. This card gains 500 ATK for each "Harpie Lady" monster in the GY. During each End Phase; destroy this card or 1 "Harpie" monster you control. 
ATK/2000 DEF/2500
 

(The card depicts Harpie's Pet Dragon rebelling against the Harpies for mistreating the hatchling. Unlike it's Phantasmal version, it prioritizes revenge until either it or the Harpies are destroyed. It disregards the harpies' commands, safety and life expectancy, this is why the card isn't even technically a "Harpie" monster.)


I know it's a long post, but i'd love to hear some feedback and if i accidentally made some degenerate loops or unfair/unbalanced conditions and effects.
