You can't play Magic with only 12 Lands, especially if you plan to cast spells without artifact acceleration. Even the Extended versions advocated to play more land, since hard-casting a Narcomoeba or Therapy is needed sometimes. This gets exacerbated after boarding, when you have to mull hands that contain the Chain or Needle, but no mana.
Cards you plan to cast:
4x Putrid Imp
4x Breakthrough
4x Careful Study
2x Tolarian Winds
3x Tarnished Citadel
