So I just picked up Marksman EB and I'm looking for some combos with this variation. The OP in the combo thread only lists combos for Outlaw and Gunslinger (which really confuses me

), and going through pages and pages of mostly Outlaw combos isn't helping. If any kind soul could point me to the right direction, I'd be hella thankful!
Most important thing about Erron Black in Marksman variation are his gun cancels as they'll get you max damage and allow you to use safer combo starters.
Gun Cancel (GC) = String xx df1~f,f+blk - If done correctly, he should cancel the startup of the df1 animation into a run. In a combo or a blockstring you immediately cancel the run into a normal.
Sorry if you knew that already, but it's worth breaking down just in case.
These are the basic combos I use (I don't use a lot as it's the oki and setups I'm more focused on), not everything but it should help you get started, there'll be more optimised stuff in and around the combo thread, you just gotta sift through a lot of it.
Overhead starters:
f13 xx GC, 2112 xx db2, f12 xx dbf2
f13 xx GC, 2112 xx EX db2, run, f24, 211 xx dbf2
f13 xx GC, 2112 xx db2, b2 xx db2, 21122 xx dbf2 (corner)
f13 xx GC, 2112 xx EX db2, b33 xx db2, 21122 xx dbf2 (corner)
Low starters:
All low starter combos are the exact same as above, only open with the low strings, b33 or b32, instead of the overhead string.
Mid/High starters:
2112 xx db2 (these lead into any enders listed above)
112, run, f12 xx dbf2
112, b2 xx db2, 21122 xx dbf2 (corner)
11b3 xx EX bf3, njp, f24, 211 xx dbf2
11b3 xx EX bf3, njp, b2 xx db2, 21122 xx dbf2 (corner)
f3 xx EX bf3, njp, f24, 211 xx dbf2
f3 xx EX bf3, njp, b2 xx db2, 21122 xx dbf2 (corner)
For any combo ending in 211 or 21122 into dbf2 you can replace with 21122 xx db3 (Caltrops). You throw the Caltrops onto the opponent as they fall meaning they'll have to get up into the forced damage. This allows you to play some nice mind games. You can also choose to throw the Caltrops in front of them as a way of either forcing the opp to jump or stay behind them.
Also any combo that ends in 211 xx dbf2, you can do the full string 21122 xx dbf2 when in the corner for extra damage.
