You can use Norra's TP to force a left/right mixup from a roll
You can adjust Norra''s 4F and 2F to land on both left or right side of your opponent from both roll options they have from a knockdown to enforce a left right mix of your choosing. (You still have to guess the roll option correctly). In this example, I set the Toph to use 2A to show this hits meaty.
- 2F catches backroll -> hold back after the TP to land in front of the opponent, or nothing/forward to land in the corner. It's important to time the 2C rather quickly after landing so you change sides with the opponent before they start the roll.
- 4F catches a forward roll -> hold back for the roll to end ahead of you (you can micro walk before the TP, but that may make it more obvious), or forward so the opponent rolls past you. This one is a bit trickier to get the meaty timing right.
I suggest using 2B as the meaty button cause that is Norra's button with the most active frames, but if you feel you were late and not hitting meaty, 2A is a quicker button that can be slightly mashed. DOn;t forget you can add the DP or throws to mix up even more with these TPs.
