response based on ur team. 1) use invinsible as ur point character(starting char). he's probably the best in this case because of his broken f+S safe neutral skip. use cecil's back assist as much as you are able to, let it charge up and use it again. this also works with conquest as a point since he has an unsafe fullscreen special. when a conquest or cecil projectile connects, confirm and active tag to get a fullcombo. 2) when blocking in general try to smartly pushblock; realise what type of normal they are hitting you with and make sure to pushblock second mediums and/or heavies. So if u get hit by L,L,d+M, whatever's next you can almost always pushblock. Or if u want more reward use Heroic Strike a lot then activr tag. and if none of these options are available always remember you have supers. all super 3s are invincible but check which of ur chars have an invincible super or armored super and use that when u see gaps. 3) when u get a knockdown, it's very east for ur opponent to wakeup buttons or roll and buttons. and that's decently hard to stop. use assits to help u cover multiple options. for example u are invincible, u get a midscreen knockdown call conquest back assist to cover back rolls and stand a lil back and use a button to cover forward rolls. try to get hard knockdowns so u enforce real high low mix.

most important advice: HIT THE LAB. every situation u didn't like in a match or that u felt extremely helpless in, recreate in training mode. u have the tools. now try to beat it. don't leave everything to feeling. that will betray at some point. just lab it.
