Maybe I don't have the rules down, but for Noble, can't you only have 4 Uncommons?

The Noble format uses lowest printed rarity to determine card legality. Both Ashnod's Altar and Ornithopter have been printed as commons, therefore they do not use any uncommon slots. The true uncommons in this deck are 2x Thopter Foundry and 2x Sword of the Meek.

Just to clarify; Mind Stone was printed as a common in Weatherlight, Oblivion Ring was printed as a common in Lorwyn, Ornithopter was printed as a common in Antiquities, and Ashnod's Altar was printed as a common in Chronicles. You did make me second guess myself about Ashnod's Altar because T/O has it listed as only being an uncommon, I had to go to Gatherer to find out what set it was common in, lol.
