Maybe this has already been brought to everyones attention. But while researching my token question I stumbled across these two rulings:
Non-Spellcasting Area
The effect of "Non-Spellcasting Area" includes Ritual Monsters and Fusion Monsters that do not have effects, as well as Monster Tokens.
Emissary of the Oasis
A Monster Token is a Normal Monster, but a Ritual Monster without an effect is not a Normal Monster.
So Ritual Monsters without effects are considered Normal Monsters for Non-Spelcastin Area but not for Emissary of the Oasis? Ooookaaay.
