I just replaced a defender of argus for an Ysera. She also works well as another win condition.

Just noticed Sparring Partner + The Black Knight synergy, very interesting!

If the Meta get more control Heavy, I see a lot more low damage Legendary being ran. (Ysera, Black Knight, Dreadmaw, Chillmaw, Sneed). Do you think Rend Blackhand would be a better fit, seeing there are several big Dragons already. Also he would be a bigger body to pop from Varian, a Rend without Battlecry would be better than a BGH without battlecry. 

That's a good idea, if the meta does slow down enough, rend would be the better choice.

I definently thought about that, the ability to stay behind a wall of taunts and gain a ton of armor, but I am not quite sure how good Justicar trueheart is yet, he has such little health as a minion. But you can experiment with him in the deck, all we can do is speculate at this point, might help a ton!

Justicar Trueheart could be essential if you take more of a fatigue approach. Also, building a huge pool of armor could open up the opportunity to add a Gorehowl. Spend your early game removing minions and building armor, then cash all that armor in to pull bigger threats off the board turn after turn with Gorehowl.

This is true.  I would definitely consider removing the Twilight Guardians for a Justicar Trueheart.  Perhaps add a second Fiery War Axe.

I have played the dragon control warrior, from which I know that you need at least 3 big dragon to make the deck consistent. So replace argus with some big dragons. 

This is really close to the deck I want to run. However, I believe I would replace the 2 Defender of Argus, probably with something like Ysera and Sylvanas. The reason for this is I don't see too many amazing targets for Defender of Argus, and you are only running 1 Bolster, so it's not like you're always going to be able to get those synergies.

Also (as said by others), Varian Wrynn gets significantly better if you are running less battlecries and more big beefy minions. I just want to be greedier :)

Yeah, I am not sure how good argus will be. If you want to make any replacement's be will probably be the first to cut, But it goes with the taunt warrior theme, and may work better than we think. 

What about hogger. 

I like the way you think :) Might be able to replace an argus with it.

If you are bothered with losing battlecries from Wrynn, I reccomend you read this: https://www.reddit.com/r/hearthstone/comments/3h4lo6/regarding_varian_wrynn_and_battlecries_and_fel/

 Wrynn helps overwhealm the opponent with minions in one turn, which also gives you value with argus. Or it could even just draw 3 spells. No matter what happens you get some value.

very nice deck:)
