A control warlock list combining 3 great packages:

The dragon package for healing and AoE containing Crazed Netherwing, Alexstrasza, Nether Breath and Circus Amalgam. You can add Runaway Blackwing here for more late-game power.

The soul fragment package for healing and early-game board control containing Spirit Jailer, Soul Shear, School Spirits, Luckysoul Hoarder and Soulciologist Malicia.

The corrupt package to beat other control decks and provide large late-game swings containing Luckysoul Hoarder, [Hearthstone Card (Cascading Distaster) Not Found], Strongman, Tickatus and Y'Shaarj, the Defiler.

Other good control warlock cards like Armor Vendor, Mo'arg Artificer, Hysteria, Dark Skies, Envoy Rustwix and Twisting Nether.

Possible cards to include are:

Felosophy for an even better match-up against other control decks to copy Envoy Rustwix or Tickatus.

Strongman to give a strong swing turn with Twisting Nether and to make Y'Shaarj, the Defiler give taunt minions.

A second copy of Hysteria to give even more removal.
