the grail with fire raimbow is to unlock level 11 of bond, and the keys of colors are part of a mechanic that consists in giving special effects to the deck of a servant, with them unlocks the power to place a command in said cards, each command has a special effect.

The keys are used with your best servants and many people do not even use them (I am one of them), they are not something important so do not pay attention at least now
