Well there was the 2016 Xmas re-run after the Mecha Halloween where you could've at least picked up 4 Holy Night Dinner.

Also you only asked "good CE for her?", so West gave you his answers on the good CE for her, not the "good CE for her that you may have (but none of us know)".

Anyway back to your question, assume you have none of those event CEs, for critical damage you can either use the 4* Gem Magecraft Antumbra or 3* Rin's Pendant.

And here's the list of CEs, you can browse to see which one you have and is good for JAlter.
