My bnb moves
Aga. No brainer. old school BNB
3B, although it is now i20 instead of i18, which is OK because he has more stance options now.
A:b. Wow this move TC's a lot of stuff, is i18, leads to base old and can K as a combo on normal hit. Leads to stance mixups. Seems to land all the time for whatever reason. Hit's OTG.
K for no other reason than being his fastest move from standing at i12.
BB or just B. i16, decent range, combos on NH, awesome poke and staple since forever, will RO as well, and can occasionally stuff RE ( I've done it several times)
2K no brainer
1K. More damage than 2k, leads to CH, and K:b follow up is uninteruptable if I'm not mistaken. Hit's OTG. I like it.
3A/ 3A:4. 3A it's hard to go wrong with a decent range horizontal mid. 3A4 has more range and damage, and attacks from the other side, but is much slower.
4A. i14 decent range horizontal that KD on Counter hit and can RO. Useful near the edge when AGA would push them the wrong way for a RO. Never go into stance, transition is too slow.
66 A+B. Long range. Decent Oki, combo finisher, hit's OTG, good guard damage.
22/88 A. Another horizontal mid that is safe I believe (maybe at tip range only). This move also TC's and I have ducked under grabs with this. Good RO and wall splat potential.
6A variants and mix-ups
Dark legacy is cheap as fuck.
Sieg is really good in this game, like... really good.
Only problem is that his meter game is lacking. His Super isn't very good, and neither is his SC game. I use SC as a keep away more than anything.
