Forum:Question about cards like Reborn Tengu and Grand Mole

I'm confused on something. I was playing someone the other day and he attacked my face down card, which was Grand Mole. When I said I activated its effect, he said I could not do that because it was face down. Why? There is nothing on the card that states it has to be face up to use it. The same goes for soemthing like Reborn Tengu. I see this on the rulings page:

■ This effect does not activate if Reborn Tengu is returned from the field to the Deck. [1] ■ This effect does not activate if Reborn Tengu is removed from the field while face-down.[1] but that does not make sense to me. How are you supposed to know the effect does not activate if it is face down or returned to the deck? The card just says what it does without any specifics like that. If it is going to be in the rulings, should it not be stated as such on the card. Grand-Mole should read:

At the start of the Damage Step, if this card battles an opponent's monster while face up: You can return both monsters to the hand (without damage calculation).
