You pose a very strong argument. It's been fun debating this ^__^. Although, I believe Pit still has some options against your SHL.
We have more options than just shooting an Arrow or approaching against your SHL. We can also use our reflectors. After studying a little I have found some interesting facts (you probably already know about them, though).
We can use our AR, which has more Surface Area and has more of a chance to deflect your SHL. It does take more time to put away than Mirror Shield if you press the B button more than once, though. Although, instead of putting it away, we can keep it up to defend against a possible attack from you. Our Angel Ring clanks with your dash attack, which is a good way to even the playing field. Your Dash attack CAN, however, go through our Angel Ring, but only if you use your Dash Attack JUST before getting hit by our Angel Ring. Considering how precisely you must time this attack, it is not likely that someone will go through each time if you do use your Dash Attack. Your Illusion attack also clanks with our Angel Ring, which will in turn even the playing field for both of us. Also, if you do not space correctly and hit our Angel Ring during the ending animations of Illusion attack, your attack will not clank with ours. Instead you will be caught in it and receive damage. The only attack you have that DOES beat our Angel Ring and knocks us out of it is your Usmash. So, this is the only thing that you can use that can guarantee a hit if we use Angel Ring.
Our Mirror Shield has less Surface Area, but in my opinion takes less time to put away. Although, we can keep it out for a longer period of time, just like Angel Ring, and we can angle it. Mirror Shield has less of a chance of deflecting a laser, but if it does, will reflect it at twice the speed and cause twice the amount of damage. If we leave it out to defend against an attack, I believe it will give us a better defense than Angel Ring, even though it cannot damage you in return or clank with your attack. If you try to use a Dash Attack, our Mirror Shield will block it, but not reflect your attack. So, we might have a chance to retaliate after your Dash Attack. Your Illusion will also be blocked by our Mirror Shield at any distance. No matter how close you stand to us, you cannot knock us out of our Mirror Shield. The only way you can knock us out of our Mirror Shield using Illusion is if you hit us from behind. Considering you would have to jump to do this and give us enough time to retaliate, I'm sure that's out of the question. The only thing that would be able to knock us out of Mirror Shield is (again. Gosh you have such a useful move) your Usmash. But, you have to position yourselves RIGHT NEXT TO US for you to knock us out of our Mirror Shield. If you do not, the damaging frames of your Usmash will only hit the Shield, and not Pit himself. Considering that you will also cause Pit to slide back if you hit the Mirror Shield with your Usmash, you will give us an opening. Please note, that your moves will not be reflected with the Mirror Shield unless you hit the Mirror Shield during the first few frames after it comes out. I'm pretty sure you can also grab us out of Mirror Shield
In my opinion, keeping the Mirror Shield out to defend against an attack is better than keeping Angel Ring out. Mostly because we have a chance to defend against a Usmash with the Mirror Shield, and the Angel Ring wouldn't defend us against a Usmash at all.
I think this might be a good retaliation against your suggestion to overpower us since it does take time to put away our Reflectors. If we don't put our Reflectors away at all, we can still defend against most of your attacks. I hope I've provided a detailed enough explanation for this. I'm pretty sure this would also be a good way to bait Fox to approach.
And I'm sorry that I can't answer your question to how Pit has more stages in his favor. I agree with what the MU thread says, though. I'm sorry I can't be of much help there.
Wow, I typed a lot
