Gaming I got the equivalent of a $10 card. What DSi Sare do I buy?

[Imacaredformy2ds]

The title says all. Most likely, I'll get a new 3DS on Christmas because my 2DSs circle pad stopped working and the R button is unresponsive. I don't know what version the 3DS would come with if I were to actually get one as a present, what would be the best course of action? I have my 2DS with A9LH and Luma 6.? but I'll update soon, What game do I buy before they're all pulled?
Keep in mind I'm kind of a noob
Also holy shit I meant DSi Ware not DSi Sare

Thank you for the fast af responses! I'll use 1001 BlockBusters. But can you link a guide? So I know what to do on the day

This list is actually from that very guide. There's also a chat linked for when you have urgent questions during the process

Thank you both
I just finished reading the guide. It actually doesn't look that hard
After that I just follow any a9lh guide right? Right?

I suggest you follow the guide from start to finish. The system transfer process is a part of the guide
