If the 5CC > jCC loop is done near the max possible range you can j.8C to beat a mashed out AC and punished a whiff 360/720 or 2C, I also manage to get 214A~B to work after j.CC and keep the 360A facing the wrong way a few times but it could had been luck.
MATCH-UP STRATEGY!
First off do not jump in or attempt to use AV to get in against Tager, it's basically a free 2C or collider.
Approach:
Getting in on Tager generally leads into 3 things
-Dash 5A/2A: outside of 5A hitting tager crouching it's self explanatory.
-6C: Against Tager trying to "zone" with his normals like 5A/5C or 5D/j.D, 6C can be cancel into AV on block to get in, corner push on trade and and can lead to big damage on CH (on normal just 214B > j.AB > jc j.D)
-Walking (read: IB and/or parrying)
Tager's normal aren't exactly on the fast side, his "pokes" makes him the perfect target for for parry since his vulnerable to the "snap" effect even from a distance.
Against 5C/5D/4D/6C just parry and if it's done from far enough you can combo from the level 3 with 5A into 2-3k damage, however 5C can gatling into other normals or drive if done from enough. This is where the fun stuff start, if for some reason they go into 6A, 3C, 6C, 6B, or 4D you can space counter the whiff and if fatal you can combo into 5B > 6A > jc j.CB > jc delay j.B > j.623C~D(whiff) 5B > 6A > whatever into 4k damage or if you good at the 2362366D input you can going into some ridiculous 9k damage combo or so. If they gatling into 5D you can let it whiff then do space counter level 1 or stay neutral, do the same if they going into that spark bolt charge state. If they 2D just stay neutral and 5CC when you recover.
Pressure:
-Try to avoid using her BnB as a blockstring, if you want an overhead just go for a tick into 6B or just flat out use 6B instead of 5CC, also can use 2B > 214A~C~A.
-When using 5CC try to delay the timing of the second C to avoid an IB, Tager's 360's can only grab you out of 6B on IB, 720 is a threat at all times. In case of IB just use 214C~Barrier (you cannot be hit out of start up due to hitstun). Another option if you have a good reaction and 50 heat is to buffer particle flare and hit D when you see his arm going for a 360's/720(is harder to notice)/2C or collider.(not recommend)
-3C/j.2C/236A~D or 214A~C~A on block is not in our advantage with tager, jump cancel that shit.
-Use Tager specify combos like 5CC > j.CC or combing 214A~C~A > 2D(3) on crouch.
-Corner oki on Tager is stronger then on most due to cosmic cannon picking him off the ground if he doesn't tech.
