Edit: finish editing later cuz i'm lazy~
Pretty disorganized here. You'll have to edit the combos a little bit so that it will work on some characters, but I'll just throw some stuff here for now and put in that other stuff later.
The Building BlocksThese normals I'm about to mention are effective, hitconfirm normals that you should always use to start any of Miyako's combos, unless it's not required in a situation. Thus for a lot of the combos listed, I have omitted them. Add them when necessary.
2A - Miyako's fastest normal that hits low. Chains almost into everything, most importantly into itself so one can easily hitconfirm after two to three hits. You'll be using this one the most.
5A - Basically like 2A but doesn't hit low obviously, thus there's less emphasis on using this one, although it has slightly more range than 2A.
jB - Mainly used for crossups. Tends to whiff quite a bit against crouchers, so watch out.
jC - Leads to a lot of pain. Links into pretty much anything. For more damage, reverse beat into jB. Do that especially if your too high in order to keep frame advantage. Use this against crouchers as it won't miss.
As I said, I omitted some of these normals where they should be in these combos. As you see with combos starting with 2C, 2A should be in front of 2C or 5B, and jB/jC in front of 5B.
Midscreen CombosAirthrow combos2C, 5B, jBC, jc., jBC air throw
-The standard, reliable, meterless bnb. Works on everyone.
2C, 5B, jABC, jc., jABC air throw
-Does a bit more damage than the combo above, due to jABC being the most damaging juggle that can be done in the air. Somewhat tight. Timing on everything in the air is pretty fast. Seems maybe character specific?
2C, 5B, 2B, jBC, jc., jBC air throw
2C, 2B, 5B, jBC, jc., jBC air throw
-Does slightly more damage the combo above. Seems to be more difficult to land on some characters when at a farther distance (e.g. Nanaya). Character specific?
BNB punish combo
5B 6B 2BC 5A jABC jc. jABC air throw
2C 22A juggle
*Only works on both Hisuis and Satsuki*. Nets a bit more than the standard punish combo. Add in a jump-in to the combo and it will do close to the same amount of damage as a wallslam combo. On Hisui, you do +550 more damage compared to the standard punish combo.
5B 6B 2BC x 22A 5A 5B 2B jBC jc. jBC air throw - Timing is noticably tight on Hisui.
5B 6B 2BC x 22A 2A 2B jCB jc. jBC air throw - Slightly easier while neting slightly less damage.
623C combos
5C x 623C jBC airthrow
Knockdown combos5B, 6B, 2B 5C x 22A
-Just anything that goes into 5C (2A, 5B, 6B, any b attack). An air throw combo will do more damage, so go for this if you want a guaranteed knockdown. Best option to setup high/low mixup, especially for fuzzy guards.
Throw combosGround throw 5C 22A
-Not worth it for the damage. Do it if you want a safer situation to activate heat, I guess.
Ground throw 2C, 2B, jBC, jc., jBC air throw
Ground throw 2C, 6B, 2B, jBC, jc., jBC air throw
Ground throw 2C, 2B, 5B, jBC, jc., jBC air throw
Corner CombosAirthrow combos1) 236A -> 6A wallslam combo (corner)
5B, 6B, 2B, 2C x delayed 236A -> 6A, 5B, 2B, jA, jC, jc., jB, jC
2) 214A wallslam combo (corner)
5A, jBC, jc., jBC
-Reliable and easy.
2C x 214A, 5C, j7A, jC, jc., jB, jC
3) 214C wallslam combo (corner)
5C xx 214C, 214C, jA, jC, jc., jB, jC x air throw
-Do the second 214C as soon as you can.
4) Near fullscreen
5B, 6B, 2B, 5C xx 236A -> 6A xx 214C [ender]
-You can delay some of the normals a bit, and especially 236A -> 6A to travel farther.
Specific enders:
a) 2B, 5C, j7A, jC, jc., jABC (corner)
*j7A assuming your on 1Pside.
similar enders:
j7AB, jc., jBC - Weakest damage but reliable.
jBC, jc., jBC - Most damaging but difficult.
b) 5B, 2B, jB, jC, jc., jB, jC
-Easy ender. Do it when you don't have confidence in doing #1.
c) Dash, 5C, jB, jC, jc., jB, jC
-Use if you think that dash -> 5C will push you into the corner.
d) 2C, 5C, [5B, jB, jc., jB, jC/...]
-Character specific. Works on Ciel, Satsuki, Nero and Warachia. Timing is late.
