Any good way to exploit Lewena's AI?

[Critical-Limit]

Because it's RANDOM/CHAOS. There is no clear cut strategy to give.
All I can give you is what I posted in the other thread.
Look at her cards. She is weak on the RIGHT side, and the Bottom side on almost EVERY single one. So place your crap cards mid-left, top left. Bait her, capture her cards. If possible recapture your crap cards with your slightly stronger crap card. But only when there is only 1 slot left to take over. If your weak card is exposing 2 sides. be careful re-claiming a card that has 2 exposed sides. Sometimes you if you think about what they have left it's worth it.

For instance.

Say you place, Cactuar card in top left corner.

She chaos' garuda/odin/Terra (Weak on bottom cards). She'll either place it under cactuar like an idiot. or place it safely somewhere on the bottom. If she places it underneath cactuar and captures it. Well now you can capture gaurda/odin/terra from underneath easily. And the reason you want to capture Gaurda/Odin/Terra instead of RE-capturing your card. Is because If they used Garuda/Odin/Terra the chances of getting one of these again over Cloud/Ifrit/Titan/Onion Knight/Bartz is low. So if they Recapture your top left card, or ANY card since they are all on the left side, they expose themselves. If they play it safe, you can freely re-claim your card. now you'll have a lead.

I could go on and on about the possibilities. But with foresight/skill/luck. You can get a comfortable win ratio against her. Nothing super amazing. But not where you feel like you're only winning 2-3 per window.
