Harpie Lady can be consisted of the Normal Harpie Lady, Harpie Lady 1/2/3. Harpie Dancer’s card name becomes “Harpie Lady” while it is on the Field or Graveyard. Cyber Harpie Lady’s card name is always treated as “Harpie Lady”. Currently only these archetype has the most potential in benefiting from Phalanx Pike ATK boost, because Harpies archetype has the most monsters that may share a name.
Typically, you can use Phalanx Pike on Proto-Cyber Dragon as it’s name is “Cyber Dragon” on the field only. Cyber Dragon Zwei’s card name becomes “Cyber Dragon” when it is in the Graveyard. There is still potential for this archetype because cards like Cyber Dragon and Cyber Dragon Drei may be released in the future, in which there will be more monsters that share the same card name.
You can also use Chain Destruction as a tech card to destroy all the cards from your hand or deck that has the same name as the card being summoned to the field, to fill your graveyard faster.
Harpies Archetype also has card’s like Harpie Harpist and Harpie Queen which also shares the same card name, these monsters were seen during Elegant Mai event, which may be released in the future.
You can also use Generation Shift to destroy 1 face-up monster you control, in order to add another monster with the same name from your Deck to your hand.
I agree with Skull Servant.That's also what I had in mind.
I like this cause I want to try it on bubonic vermins and dragon troop. So that they defend while buffing the attack as Well. N you can Probably equip the spell cards that let's cards with 1000 or less attack attack directly before equipping this one
