Well, I would easily know a better set that would have very diverse shapes and be more suggestive of the powers:
Pincher Pawn -> Go stone
Long Leaper -> Draughts King (i.e. stacked chips)
Chameleon -> Mirror
Coordinator -> Radio-telescope dish
Immobilizer -> Horseshoe magnet
Withdrawer -> Rocket
So if we are bent on introducing new sets that have never been used before, we better give it some thought before acting rashly. We are not married to Alfaerie, so "best set using Alfaerie pieces" is a meaningless distinction. That a piece set has dedicated Ultima pieces would be a reason to show them 'under a button', but if they are not much good we should avoid their use (and thus the use of the set they belonged to). Beside that, we should just present the set that is best without limiting ourselves to existing images from existing sets.
