There are no better M&M credit cards in Germany than what's listed on the M&M site.

But if you are a US citizen, you should be able to get the US card if you want to jump through a few hoops.

1. SSN (you obviously have one if you're a US citizen)
2. US mailing address. Use a friend/family address with c/o
3. A way to pay bills. Get a checking account again, you can open one online at many banks as long as you have 1. and 2. Or again, pay via a family member's account. CC company doesn't care where the money comes from as long as they get paid.
4. Set up paperless billing to not annoy your friends with too much mail and avoid snooping.
