Sadira main since season 1:
Alot of her pressure is overrated IMO. The only time you should really be worried is on knock down (Fulgore v Sadira). Just try your best to block because 90% of that stuff is reactable, not to mention the stuff that isnt is punishable (aside from some really high execution mixups). AA is super important but you have a DP so actually your job isnt as hard as it could be. If she throws MWB its punishable by L DP. It has way less block stun than you think it does. There are some specific ranges where she’ll go over your DP, but she has to be pretty close to you for that, and that kinda means she won the neutral for that to happen. If she does jump in LWB shes negative on block, so just hit lk and go nuts. I would say just do DP if you see her jump in neutral until she starts baiting it with jump forwards and then jump back or jump MWB. Then once they commit to that mind game, if you think shes gonna jump back, just chill and block, react to the jump back and then backdash to gain space. If you think shes gonna MWB, just block and punish. Worst case scenario is you guess wrong and your on defence. On defence if shes just doing jump HK over and over, jump back LP, or LK. Mind you thats only if you have a read.
In neutral she cant really do a ton to stop fulgore, She can usually keep people out by throwing HWB but fulgore can just H eye lazer through, so thats not really a solution. I also think using M eye lazer is good as a poke, because it can be hard to react to and it beats alot of sadiras options (I think you can pip cancel it into DP yah?)
Also, I havent played KI in a while so take what I’m saying with a grain of salt. But I also remember fulgores H DP having a ton of invincibility, so It can probably go through alot of Sadira’s projectiles.
