My experience with Beckoners comes from playing Lynch and Zoriada. Their cost is high if you compare them to the other lurers in Belle's and Oiran but the price is justified due to the other abilities they have. They synergize brilliance with themselves with Don't bite the hand, Sweetest fare and The party never ends but the main difference they have and i feel where the value lies is Not that kind of girl. For 1 AP you get a lure and she can push herself around making her very effective at pulling her own crew forwards, especially if you have a way of getting her forward without using her own AP. Combined with the Doppelgänger you have quite a lot of luring potential.
