Are you really trying to mill your opponent? I would take out jace's erasure for 2 Kami of the Crescent Moon if you want a low cmc card. If you aren't worried about that there is Thought Gorger and Aeon Chronicler . You also gotta have Sign in Blood . With notion thief you can target them so they lose the two life and you still get the cards

I feel that by combining Jace's Erasure with the Jace's Archivist + Notion Thief gives me another win condition than just straight damage.With a full hand, I can be milling at minimum 14 cards a turn (more with more copies), which is pretty nice. However, 4 may be too many in this deck.

I might switch two out for either the Sign in Blood or possibly Dream Fracture for the 2x card draw and counter spell. I like the Kami of the Crescent Moon , but I don't have any sitting around at the moment to add them.

I see, I build my decks on here exactly how I like them then work towards that. Either way, here is my notion thief deck I recently made. squidies
