I'm just going for high resistance on my Jizoh, and proceed to pound her to pulp... That's my go to  tactics, having deflection set on one of your team member also helps, having that dec def bounce back at her is just the best thing.

try to put together a shield set on a champion so her ai uses her a2 instead of a3 first! that should significantly increase your odds of winning!

Funny, I'm sometimes tempted to do the exact opposite - remove the shield set that I usually have on my MK so as to avoid her opening with that terribly annoying A2. I'm not that bothered by her A3, far more by the A2's true fear on my team and block debuffs on her own. Of course the A2 is a lot more RNG-based, if you repeat the fight a few times you'll get a fight sooner or later where it fails apply on any champ and hence doesn't place the block debuffs, but that's not exactly an efficient way of using resources. 

the way to beat her is to avoid any battles against her

I have her  but she is only in my tag team  on the third team

When I see her  in classic arena  I do not shake in fear

speed , speed , speed  = Go first and destroy the competition
