Overall is a useful guide, but there are some aspects that are not correct in some cases:
-Uair is also a great juggler
-Fair is only 3 kicks
-The Dair spike it is not at the toes. It spikes at Dair6 (6th hit of Dair)
-Also, if you land before finishing the Dair animation, DairF will come out and has a very decent hitbox to keep away punishers.
-USmash does not has the same application as the Uair, since Uair does not true-comboes out of any move. Maybe Dair, but practically any move comes out of Dair
-Spit out of inhale does not make more damage. Copy Ablity and Spit both do 10%
-Final cutter is the only projectile, but you forgot to mention that it spikes in its way down
-Stone is not good to get back on the stage, only if you bait your enemy to charge a smash attack or if you are really coles and really good at reaction to a tilt. If it is neither of this cases, you can be severely punished with a grab or even worse, have a habit and be read more frecuently.
-Dthrow no longer is, if it has ever been, a combo starter. Fthrow is better
-Bthrow IS your kill throw.
Try using this info to develop a good combo guide, these are some tips that not many people kow, but i do explain them on my guide. If you want to know more of the char. check my guide, I explain the uses of many attacks on it:
