Questions about Legend Box

[SomethingElse]

Just wanna clarify some things about Legend Box....
Can you play Box even if your bench is full?
How about if there's less then 10 cards in your deck?
If you sucessfully find a Legend, and attach a Rainbow, does it take 10 damage?
Does Lugia Legend's Poke-Power trigger from Legend Box? If so, finish Box first, then shuffle and apply power?

Can you play Box even if your bench is full? No. That would be playing a card for no known effect.
How about if there's less then 10 cards in your deck? Yes. You do as much as you can.
If you sucessfully find a Legend, and attach a Rainbow, does it take 10 damage? No. You're not attaching it from your hand.
Does Lugia Legend's Poke-Power trigger from Legend Box? If so, finish Box first, then shuffle and apply power? Yes, it does not require that you play it from your hand.
