I was thinking a dual deck of sakrohm and uppers:
Is that a good choice/start?
Montana is pretty good for starters, easy to use.
If you have Uranus, and Mokra, Sakrohm is definately a great start too.
Uppers will be a good clan to practice your deck building, since it's also easy to use, but harder to build.
Frozen can be hard to master...
Your deck here is fine, go play some and try to adjust based on what happens
Maurice or kazayan is better than nellie though.
