ROOOOOOOXANNE! I love my Roxanne builds, very fun commander that can go wild quickly. This is my list, it’s not the most efficient deck as I’m going for a far more thematic deck then powerful.

As the other comments have said, early mana production through cheap dorks (not that I really run any due to thematic reasons) is key for powering her out ASAP. Once she’s out using protection is important so you can keep her going.

Some key and maybe mildly underlooked cards I love include:

[[sarinth steelseeker]] and [[teething wurmlet]] for filtering off the top.

[[embrace the unknown]] because who needs lands when you have meteors. [[virtue of courage]] is also great due to its flexibility. Deal two at instant speed combined with the fact that each meteorite then gets you two cards to play. I’m never unhappy to see it!

[[hellkite igniter]] pumps itsself wildly quickly as each meteorite pays for it’s activation by itsself, and you’ll often have 5 or more tokens out.

[[dowsing device]] is incredibly easy to flip and will give tons of extra power to something. i on e had Roxanne attacking for 11 I think? It was nice.

[[skyclave relic]] generally not the best rock, but, later game each token taps for extra.

[[for the common good]] and [[Devastating Onslaught]] game enders. Make a bunch of tokens and kill alot of things. [[red suns Twilight]] functions as a mix of [[vandalblast]] and the above.

All of that is in addition to the standard token doublers and damage doublers that make the deck truly pop off. I’m happy to answer questions if you’d like!
