CMD Players cant draw (EDH / Commander)

Hope you will get my explaination - my english is a bit rusty... ;)
Key-Card is the "Maralen of the Mornsong", which says that no Player may draw cards. Instead every player may look his library for a card and put it into hand. In addition, each player looses 3 life. I'll work against this loose-life-effect with "Exquisite Blood", which gives me everytime life equal the amount of life my opponent lost. So it's equalized.
To even worsen the opponents worries each turn, we can play "Wound Reflection", which doubles the damage once each turn.
If we have enough mana, we play "Ob Nixilis, Unshackled" on the top. It says: "Whenever an opponent searches his or her library, that player sacrifices a creature and loses 10 life.
Whenever another creature dies, put a +1/+1 counter on Ob Nixilis, Unshackled." So your opp. has to sacrifice each turn und our "Ob Nixilis" becames more and more powerful each turn.
We try to fasten our abilities up by several mana ramps while slowing the opponent down by enchanting his lands.
Furthermore we make him mad by several "must-removals".
The really nice thing about this deck is, that we can search our library for cards which lets us trigger best combos with our commander. Sure, the opponent may search his library, too, but our Commander costs only 3, which hopefully gives us a powerful advantage before the opponent has.
