What if they just bring back the old card effects and whenever we use a specific card (ex.: Bole) on a player, this specific player gets the defence buff and we earn a Bole Seal. Then, after collecting from either 2-3 different card seals, we then give 2-3 different buff effects to the whole party using Divination. But when we collect 3 of the same seals from a specific card, for example Bole, then the Divination we use will place a stronger defence buff unto the party.

So, Squeenix doesn't have to remove Divination and just revert the card effects.
