I will not judge move based on their utility in combo but more in their raw interest to use it in a non-combo situation.
My personal top ten :
1. 2363B/33B, Everything with that attack is godlike
2. Throws, aPat throws are one of the best of the entire game, Strong RO capabilities, can lead to 100 damages.
3. 2363aB/JFT, Amazing punish and rushdown tools, did i mention its awesome range ?
4. 66B, Safe mid that hits hard and tracks rather well, rather good range.
5. 1AAA, One of the best low in the game, RO and wall combo potential, also invisible, only downside : slow.
6. CE, i8 lol. It can win games by itself.
7. 2143b:B, Tech crouch, fast and good damage, rather safe, perfect to stop people that spam very fast attack with not a lot of frame disadvantage.
8. 2A, Not a glorious move but its utility is very strong, that's your little fast poke that just stop your opponent from going wild.
9. bA, Good zoning tools and rather safe against a lot of characters. Really useful.
10. 4K/3K, Not a glorious move too, but it's the best stepkiller of aPat IMO, very underestimated,, just because it hits mid, it counter near all of the Evade attack (Ex : Ivy's 3B), and kill players that abuse those moves too much. it's fast, give good advantage (Spam it as long as the guy don't want to block it). it's more a psychological tools than a damaging one, it still fits very well in aPat arsenal.
Some other good :
1B:B would be strong if i can use it consistently one day.
Silver Moon combo is more than decent against people that can't punish hit hard, you use your 1AAA and pray your opponent duck and BOUM 82 Damages.
8A+B B, You're going to kill people that don't want to stand up with it.
2K because i use it all day like a scrub.
