So I assume ???/Polished/Gilded are different tiers of the mod? So a Gilded Divination Scarab would be 300% more div cards, and a ??? Breach Scarab would be 1 additional breach.
Edit: Also the flavor text mentions the Order - presumably the Order of the Djinn? These might be related to Jun's content, so not available in Standard.
Rusted, Polished, Gilded - yes.
