Queen Marchesa Optimizing

Hey guys,

I am looking for tips and recommendations for my Queen Marchesa deck. I attend a LGS from time to time, but I usually play with friends. I have put a few cards in the sideboard that I already own and might be worth considering. Other than that, I'm happy to receive recommendations of any kind. My first ideas were to play a more Enchantment-focused deck, maybe also in the direction of Treasure Tokens.
