Inconsistent how? Even if you only see 1 in a game, it's not going to wreck the game for you... but the games where you actually get to draw 3 cards from it should justify inconsistency's. It's not that AK is amazing in the deck, it's that it's the only realistic form of card advantage that is available. 8 cantrips are plenty enough cantrips... more cantrips will increase card quality further, but the deck needs card advantage far more.

EDIT:

Look you can't hope to support a 4 color mana base on 18 land. Confidant is great card advantage, but is totally wrong for this deck. We have no out such as cabal therapy should the life loss get dangerous and no way to seriously exploit him such as sensei's top. Also with only 7 counters and zero stifles (to deal with ringleader, EE, ect.) you have no hope of protecting him, which means he won't generate the card advantage you want.

As for Accumulated Knowledge, I don't see why were still debating this. AK is a terrible card if it isn't with Intuition. The argument that the first one is bad tends to exclude it from competitive play, as you never want to run bad cards.

A core of the deck has already been agreed upon, tested, and proven. Wild alterations to the deck ,such as changing its colors or lessening its counterbase to less than 7 counters, are counterproductive and cause all of us to take your opinions with a grain of salt.
Wow okay I was just tossing some random ideas out, not trying to "ruin" your deck and make you discredit my trying to help you. I'm gonna just stop posting in this thread now.
