Control Cubelock

So basically every card from this deck is cards from Cubelock except Stonehill Defender and Acadic Swamp Ooze. The reason why I put ooze here is to destroy an opponent Cubelocks weapon in mirror matchups. Stonehill Defender is the best turn 3 a Cubelock will ever make though, although it is not a board clear you get a 1/4 taunt body as well as discovering even another Voidlord for the Skull to summon. 

Another thing is Lackey. If you look closely in this new version, not only Dark Pact can activate Lackey, and I am not talking about Cube. Dark Possession is one of the best cards that can be used in Cubelock, though the tier 1 deck doesnt use it. It not only can one shot Lackey, but can also discover a Doomguard for the Skull to summon!

Also, you may say Despicable Dreadlord shouldnt be here, but if you are out of Doomguards and Voidlords, and used your DK, this is the hard removal. Remember to cube it and Dark Pact, you will eventually get 4 Despicable Dreadlords that casts Flamestrike!

I dont really need to say about Doomguards and Voidlords, but Bloodreaver Guldan. Never play your DK if no Doomguard or Voidlord died, but when at least one dies, play it. The reason is that if you dont play your DK by time, you will only summon a bunch of Voidwalkers.

Optional Cards

Spellsinger Umbra is a good replacement if you dont like Acadic Swamp Ooze or if you only need one Dark Possession. 

Faceless is another good option but in here I prefer Despicable Dreadlords.

Although Rin, The First Disciple is not listed here, she is also a good card if you are in lack of cards. But you can always discover her in Stonehill Defenders!

The other card strategys I really dont need to mention because Cubelock is already a tier 1 deck and there is no way you dont know how to use the rest.
