I keep wondering whether a LB Lunchtime on a Waver/Merlin would net more use/FP in the All Slot or Caster Slot.
I mean, if someone's just looking for any LB Lunchtime, they're more likely to take a Jeanne Alter or some other grailed Servant in the All Slot. If they want Waver/Merlin specifically, would they even bother to check the All Slot before checking the Caster Slot, or only do so after ensuring the Caster Slot doesn't have one?
