Is there already a format that does what I want?

I've been playing a lot and trying to pin down what I most like to do with this game, and now that I think I can imagine what my "perfect" format for me would be, I'm wondering if it exists/has a name so I can try to pitch my friends on it.

What I think I want is:

• 100 card singleton
• No command zone card(s)
• 1v1
• No sideboard
• Affordable enough that I'm not dropping $1000+ on a deck
• Low enough powered that I can start building with cards I already have (which is mostly from sets since Foundations)

I know the real answer is "formatless, just throw 100 cards into a deck" but I think there would still be some need to level the playing field a bit since my collection is so much smaller than my friends' But surely people have ways to play that hit at least most of what I'm looking for. So yeah, I'd love to hear what people can suggest!
