I use a simple rule: Weekly, Monthly ALL Exp cards, event bought and special login reward ones = Keep in Gift Box for increased success rate events (Xmas and anniversary usually)

Class-based EXP cards, use them normally

4 star EXP cards regardless of type: use as exp

3 star ALL EXP cards: use as exp for lowest leveled servants

3 star class-based EXP cards: sell for mana prisms

Only use EXP cards by groups of 20, or 1/2 of what you'd need to lvl up to the current servant's limit. Using 20 when you'd need 21 to lvl a servant up is dumb, super/great success happen more often than you'd believe.
