There's too many taunts, and you don't really need defender of argus because most of your minions have taunt anyway. I'd remove bad or expensive cards like senjin, bog beast and drake (nowadays it's just too expensive, and mage has better clears). Skeleton package is much better for that, you could even keep argus to buff your skeletons if you insist on playing the taunt idea. And cairne is just too slow, better throw in queen azshara for more flexibility.

Also you don't really need big game hunter, 2 life sentences should be enough for hard removal. Same thing goes for pyro, spectral trainee is just enough. 

Also objection is a much better secret than explosive runes, I know you're trying to produce as much damage but objections is just better since it denies any battlecries or deathrattles which today are more important to block than bodies (mostly).  

Finally, I get shooting star adds damage for your trainee and pyro, but it's just too weak to waste a slot. I'd throw in vast wisdom for more wiggle room. 

Just my 2 cents :)

Just realized it's a renathal deck. You have almost no card draw so having so many cards cripples you too much. Try to lighten it for 9 other cards and throw out renathal (it's always hard to decide what to throw out, but some cards are just worse in the deck than others so unless you really need the 5 health, it's better to depend on 30 consistent cards).

Ah Ok, I understand.

I'm not a long Player of Hearthstone so I'm not experienced how I should build a Deck. I already changed some Cards of the Deck but I will look it again.

I will update this Deck, if I changed some Cards etc. and I want to see if this Deck got better ^^
