Mill opponent's units

Idea is to dry the opponent out from drawing any units:
1) Fallen Oni is usually not considered a threat and can be looped multiple times with Questioning Devotee, Insistent Automaton, Meditation, Pause for Reflection and Rune of Relocation.
2) Containment Sphere to lock the void. Usually, no problem if destroyed. It's the only attachment in the deck.
3) Coerce, Belltower Shot and Ziat's Advice to thin out the enemies units in his deck.
4) The Unforgiven in the Market for late game.
5) Eremot, the Gathering Dark can often be triggered with charge. If not removed it mills the opponent out of cards in a few rounds.

There are only 19 untis which are mostly weak which is why I added 17 unit removals / 7 attachment removals.
Bhodi & Rox Forever works well to ramp and becomes a kill condition in later rounds. I included it only once because drawing two in the same game felt like one too many.
I only have one Dreamsnatcher. Should probably have at least 2 in the game.

The deck has two weaknesses:
1) if the opponent has 5+ units amongst his first 10 cards it's difficult to keep up. My units are weak blockers and returning little damage.
2) milling the opponent fully out of cards takes 10+ rounds. Even if they struggle with units, they will have plenty of power and sometimes just pull something together because they have enough rounds to finds something lucky or access to market.

Suggestions & inspirations welcome.
