I was trying only to count 2-mat generic monsters, but I might have still missed something
Trivia: This card is connected with my other two fanmade cards listed here: holycrapwhitedragon.deviantart holycrapwhitedragon.deviantart And is inspired in how Atem summoned Holactie (or Horakhty)
Maybe Secret Lairs dont need that extra hype
From Harpies in the original series, which had consistently high attack stats and some great ways to consistently special summon, to Blackwings in the 5ds era, which broke synchro summoning as we know it
Also the archetype has a lot of Spells and Traps that can make up for their relatively weak attack power such as Harpie's Feather Duster, a reliable Spell card that ANY deck can use to wipe out the opponent's backrow, Harpie Lady Phoenix Formation which can destroy monsters depending on how many Harpies you have and Hysteric Party which can Special Summon as many copies of Harpie Lady from your graveyard as possible
However, further down the line, storage is going to be an issue
