I goldfished the list 20 or so times and all I can say is wow. About 50% of the time the deck killed turn 1. However, I think it is far from a perfect list for this "speed tenrdills" sort of deck.

I often found myself lacking blue mana to cast spells like brainstorm or sleight of hand. I think a cantrip castable with black mana would be far better in the spot of sleight of hand, such as conjurer's bauble. While not great I think it is better considering this deck creates so much black mana compared to how much blue mana it can make.

Props to Meandeck for coming up with an awesome idea!  

I think any sort of restriction right now would not be needed. Shop decks, control decks, and combo decks are all perfroming well now. Why go and restrict a bunch of random key components to decks if they are already balanced?

But if the cards you mentioned were restircted (which I doubt will happen, but hey anything can happen in this format I suppose) I like everyone else would play control slaver. Or, I would be smart and play a deck that beats contol slaver such as fish   .
