Tolarian Entrancer is the key here. Go up and read what he does. Whenever he is blocked he steals the opponent's creature that blocked. Super cool, right?
First...you are asking yourself some questions:
Question 1: Jessie, what if your opponent chooses to not block the Tolarian Entrancer?
Answer: Lure and Irresistible Prey makes your opponents HAVE TO BLOCK Tolarian Entrancer!
Question 2: What if your opponent is smart and decides to attack every turn with all of his creatures, thus not having any creatures for Tolarian Entrancer to block?
Answer: Jangling Automaton untaps all of your opponent's creatures when he attacks.
Question 3: Okay, okay, but what if your opponent has no creatures in his deck, how is Tolarian Entrancer going to help you?
Answer: Beast Within. It kills the opponent's best permanent, but gives him a 3/3 creature. No worries, I just steal it! Forbidden Orchard, every time I tap it for any color mana I want, my opponent gets a 1/1 creature that I can steal.
Question 4: You talk about stealing 5 1/1 creatures by attacking with 1 11/1 Tolarian Entrancer...but how does he survive 5 damage and how does the 5 1/1 creatures survive the attack? Sounds dumb, Jessie.
Answer: Math of Ith and Gaseous Form. Both of these cards prevent all combat damage to Tolarian Entrancer and to all of the creatures that block him.
Question 5: You keep talking about this Tolarian Entrancer guy, but what if you don't draw him?
Answer: Muddle the Mixture is the Search Engine that gets you Tolarian Entrancer in your hand.
Question 6: What if they try to sack/destroy/nuke/exile your Tolarian Entrancer?
Answer: Bounce him to your hand with Disperse, and he lives to see another day.
Question 7: Umm, Jessie, what if they get lucky and exile all copies of Tolarian Enrancer, you do know they make cards like that, right?
Answer: Hunted Phantasm is already a 4/6 unblockable creature, but as back up and Win Condition #2 is Stuffy Doll. For each damage done to him, he does that much damage to target opponent. So pop a Lure on him. Attack with him, and let the fun begin!
Question 8: I am running out of questions, but how are you going to draw all of these cards that you just mentioned?
Answer: Infiltration Lens can draw you tons of cards, in this deck. Picture this. You have a Tolarian Entrancer enchanted with Gaseous Form and Infiltration Lens. Your opponent has 3 creatures. You attack with Tolarian Entrancer. This is what happens. You draw 6 cards and your Taunting Elf lives to see another day, plus you get to steal their creatures!! Very brutal.
Glad to answer all of your questions. I hope you like it.
Edit: Kazzong recommended several good cards:
Forbidden Orchard. IT secures my mana base while giving my opponent a 1/1 creature, every time i tap it, that Tolarian Entrancer can steal. Good stuff!
Xantid Swarm was also added. It is awesome against blue hate and general disruption that my Tolarian Entrancer would face.
Sheltering Ancient. For 2 mana i get a 5/5 with trample! Very nice. Only downfall is that I have to keep putting +1/+1 counters on my opponent's creatures. But guess what, I am just going to steal their creatures anyways, right? Win win!!
Beast Within. For 3 mana I kill their best permanent and my opponent gets a free 3/3 creature. No worries, I just steal it from him!
