I create Illusionist Hero, hope you enjoy

There are lot of synergy between this cards. I'll show you it:

• Scorch with: Goblins Attack (Cowardly Goblin), Soul Summoner (Soul), Walking Bomb (if you have spellpower).
  Cowardly Goblin, Soul and Walking Bomb are minions you don't want see on your board, you can kill these useless or dangerous (Walking Bomb) minions and even recieve card for that.
  
  
• Setup with: Goblins Attack (Cowardly Goblin), Soul Summoner (Soul), Walking Bomb, Wall of Pain (on low health or after silence).
  Same as Scorch you can remove useless minions from your board, flood enemy board with this useless minions and even get card for this. You can also give enemy your Walking Bomb, which deal 3 damage to adjacent minion at start of owner turn, so it can kill some enemy minion.
  
  
• Immolation with: Goblins Attack (Cowardly Goblin), Soul Summoner (Soul), Walking Bomb, Wall of Pain (on low health or after silence)
  Same as Scorch and Setup you can kill your useless minions, relieving from them and get cards instead.
  
  
• Illusive Staff with: Illusive Shield, Laughter of the Gods, Royal Guard, "Illusions"
  With Illusive Shield it gives your minion nice attack and health (my minion has 5 health and both buffs, if enemy attack him with 2 Attack minion my health will be 5/7, so after attack i'll lose only max health and became again 5/5)
  You can use both Illusive Staff and Laughter of the Gods on enemy minion. If he'll try to attack, he'll die immediately.
  You can buff your Royal Guard, so he'll recieve decent damage to enemy hero.
  Buffing your Illusions with Illusive Staff is good idea, because you don't care about Illusion's Health, anyway it will die from any damage.
  
  
• Illusive Shield with: Illusive Staff, Itself, Laughter of the Gods, Bloody Corruption, Enslave the Will, Elf Protector, Second Nature, Mass Suicide, Potential Power, Wall of Pain, Vereesa
  With itself? Yeah, if you use two Illusive Shield on your taunt minion, it'll "heal" by 4 with every enemy attack. It's almost immposible to kill this taunt without spells. And what if you use it 3,4 times on taunt minion?..
  If you have low health minion you can give him time with Illusive Shield and Laughter of Gods, because after first attack your minion will have 3 health and after second - 5 health. If you don't care about attack of this minion this is nice save mechanism.
  Bloody Corruption on enemy or own minnion and Illusive Shield give you possibility damage enemy hero/draw a card a lot more time.
  You can easily reduce attack of one of the enemy minion to 0 with Illusive Shield. Then use Enslave the Will on this minion, so enemy can't suicide it.
  Elf Protector can be protected a bit from Illusive Shield.
  Second Nature - same with "itself".
  Mass Suicide. You can "prepare" some minions before using Mass Suicide, so they won't die to it. It can be your own minion, which works even with low (or 0) attack, or if you want to flood enemy board with useless minions.
  After Potential Power some minions can still have big attack, so you can reduce it with Illusive Shield.
  Wall of Pain is the best target for Illusive Shield. You don't care about Attack of Wall, but you rly care about it health. Very nice combo.
  Vereesa (and other minions, doing something not depending on their attack). Very hard to kill, seems like infinity draw minions.
  
  
• Laughter of the Gods with: Illusive Staff, Illusive Shield, Enslave the Will, Elf Protector, Clone (and any Illusion), Oscillation of Matter, Mass Suicide
  Use Laughter of the Gods and Enslave the Will on same enemy minion so he can't suicide it at least for one turn.
  Elf Protector can be protected by Laughter of the Gods.
  Every Illusion die to any damage, so you don't care about its Health, but Divine Shield can save Illusion from dying at least for one time.
  Laughter of the Gods on any enemy unit and then Oscilattion of Matter = instakill.
  If you want protect your own unit from dying from Mass Suicide you can protect him with Laughter of the Gods.
  
  
• Torment with: Illusive Shield, Setup, Soul Summoner (Soul), Satyr Traitor (Battlecry), Potential Power, Faceless Terror.
  All of this cards can be used to create or lock minions on enemy board, so your Torment will deal 5-7 damage for 2 mana.
  
  
• Enslave the Will with: Setup (on useless minion), Illusive Shield, Soul Summoner (Soul), Second Nature, Satyr Traitor (on useless minion), Potential Power, Faceless Terror (After silence),
  All of this cards can give your enemy useless minion, so you can use Enslave the Will on it and he can't suicide.
  Second Nature with Enslave the Will so powerfull combo.
  
  
• Elf Protector with: Illusive Staff, Clone (and any Illusion), Walking Bomb, Mass Suicide, Wall of Pain (and any Taunt).
  Illusive Staff can give your minion additional attack, and because you have Elf Protector, this minion won't die.
  Illusions die from any recieved damage, but not under Elf Protector's protection.
  You can protect your minions a bit from Walking Bomb when you have Elf Protector.
  Your Taunt never die under Elf Protector.
  Mass Suicide - enemy minions dying, your - not.
  
  
• Clone with: Soul Summoner, Vereesa, Elf Protector, Walking Bomb etc
  Any minion you want to live at least 1 turn. (Much better then Faceless Manipulator because 2 mana less cost)
  
  
• Mechanical Suit with: Second Nature, Gnomish Researcher.
  Mechanical Suit can absorb Mech's Abilities, Second Nature can double them.
  Gnomish Researcher make every your minion Mech, so Mechanical Suit can absorb Ysera, Vereesa etc.
  
  
• Goblins Attack with: Scorch, Setup, Immolation, Satyr Traitor.
  Kill goblins for cards or send them to enemy.
  
  
• Ghostly Weapon with: Elf Protector, Mass Suicide, Potential Power.
  Elf Protector with Ghostly Weapon gives you pretty nice trades.
  You can use Ghostly Weapon before Mass Suicide to kill more enemies.
  If enemy has low attack minions, you can buff Attack to your minions with Ghostly Weapon and lower Attack of enemies.
  
  
• Soul Summoner. Read "Goblins Attack".
  
  
• Secrets with each other.
  Because of Restoration, enemy want attack only with one minion so he won't heal you to much. But if he want play minion, he need to attack with a lot of them, because they can easily die to Infected Soldier.
  Because of Infected Soldier, enemy want play only one minion, because of Magic Leak, enemy want play only one spell. But because of Thought Destruction, he need to play as more card as he can.
  Because of Thought Destruction, enemy want to play a lot of cards. But because of Restoration, he want to keep this cards for a long game.
  
  
• Second Nature with: Illusive Shield, Illusory Soul, Bloody Corruption, Enslave the Will, Mechanical Suit, Soul Summoner, Wall of Pain, Vereesa.
  Second Nature double Abilities and Effects, so you want... double it, yeah.
  
  
• Satyr Traitor with: Clone (and any Illusion), Torment, Goblins Attack (Cowardly Goblins), Soul Summoner (Soul).
  You can flood enemy board with useless or dangerous minion and even recieve their Attack and Health.
  Battlecry of Satyr Traitor buffs damage of Torment.
  
  
• Gnomish Researcher with: Clone (and any Illusion), Mechanical Suit, World of Illusions.
  Gnomish Researcher makes all of your minions Mechs. So it's remove race "Illusion" and minion don't die to any damage or silence.
  Mechanical Suit can absorb any unit thanks to Gnomish Researcher.
  
  
• Mass Suicide with: Potential Power, Ghostly Weapon.
  If you want to flood enemy board with useless minion, you can Potential Power them and they won't die to Mass Suicide, while you'll kill with it other stuff.
  With Ghostly Weapon you can destroy enemy minions easily.
  
  
• And of course the biggest combo in this deck: Infected Soldier -> Faceless Terror. After making every minion Illusion by Infected Soldier, you make them "Can't Attack" and give enemy "Mute World" card. But if enemy use it, he will destroy his entire board - Illusions dies if somebody silence them!
  
  

For aggro Illusionist has nice early drops like Goblin-Hunter, Illusory Soul, Royal Guard and Phantom Warrior. But every drop have huge weakness Goblin-Hunter can't attack enemy hero and can only help you to def other minions by killing enemy stuff, Royal Guard can't do anything if enemy has Taunt, Illusory Soul so easy to remove after it suicide to someone and Phantom Warrior gives you opponent tool to stop your pressing.
At least you have nice buffs for early game, like Illusive Staff, Illusive Shield and Laughter of Gods. And you have 3 early game removals - Scorch, Unexpected Sacrifice and Torture, but all of them a bit to hard to use.
For lethal you have Walking Bomb with Clone and Ghostly Weapon.

But I think Illusionist has much better control tools.
His hero power give him so huge card advantage, Illusions can be very powerfull, if you create them from big minions.
Secrets a bit expensive for aggro deck, but can be very powerfull in long games. Mass Suicide can destory enemy big minions, Wall of Pain just very nice taunt when you play defence.
Vereesa and Faceless Terror can just turn the tables in late game, if you use it correctly.

And third option, how Illusionist can play is flooding enemy board, so enemy can't play minions.
You have a lot of tools to flood enemy board with useless minions - Setup, Illusive Shield, Soul Summoner, Satyr Traitor, Potential Power and of course your Hero Power, which can duplicate any of these cards.
If you will do this, only way enemy can win - direct damage, or kill his own minions using spells.
