There is a treasure chamber on B3F in the deep miracle sea! In the treasure box might be a wonder gummi, seabed veil, air blade or silver veil! To get in the treasure room you need to get the key (which you can buy it for 8000 poke at the kecleon shop).
Hope that helps!
Deoxys is on Floor 17.
It can be on any floor.
mount horn 7th floor
Deoxys' Forme randomly changes as you progress through a dungeon. The changes are purely cosmetic, except for the Speed Forme, which doubles his movement speed until you move to the next floor.
go to the bottom floor of the guide

You get him in shimmering hill floor 17 with secret slab. However he is very hard to recruit
Go to Shimmer Desert floor 20 and you can meet Deoxys(You must bring a Secret Slab.)
First, you have to get a secret slab. Once you have that, go to shimmer hill, 13th floor and find Deoxys, defeat him, and recruit him.
