and a basic circle/river packing(or box packing) of it as well:

The head/blue chest piece is somewhat complicated(even i have trouble folding it sometimes)
for the chest/body area, i suggest looking at the packing for reference.
Lastly, here are some things not shown by the cp:
-color change of the face
-thinning of the neck
-thinning/finishing touches on tentacles/arm
-the blue chest piece is sticking out from the back of the model(you have to reverse fold it inside the model)
-color change of the waist
-shaping of the legs
Good Luck!
P.S. Also, since the amount of paper for the tentacles and arms are the same, you can fold a Deoxys with 2 arms or 2 tentacles if you wanted to
