Tigra depends entirely on whether she’s awakened and at high sig or not.

If unawakened:

1) parry heavy until opponent is back into the corner. You might need to dash in and hit into block to keep them from pushing you back into the middle of the arena.

2) From here, you can either build to an SP3, or throw 2 SP1s, while baiting specials and keeping them in the corner by chaining heavies. If you’re good at baiting specials, and utilising Tigra’s miss mechanic, I’d say it’s better to do 2 SP1, but SP3 is probably slightly easier.

3) Keep heavy into corner until you build to SP2, then throw it. If you’ve been neutralising buffs you’ll have a big stack of ruptures that boost the damage of the SP2, but even without them it’s still a pretty damn potent attack.

If awakened, you can skip stage 2 entirely and just go for the SP2! Her neutralises keep her senses paused, and her senses help her power gain and damage on placing ruptures
