Why does the ladder Death Knight deck cost more money?

I have the ladder Mage deck for free, and spent $5 on the Priest one. I’m pretty pissed off about the latter thing after seeing the remaining decks have completely different prices.

What I can’t figure out is why the Death Knight deck is marked up so much. It has 2 Legendaries, 4 Epics, 6 Rares, and 6 Commons. The rest are free cards that aren’t granted by the purchase. This is priced at $16.

Meanwhile, the Warlock deck has 2 Legendaries, 4 Epics, 10 Rares, and 8 Commons. $11.

I don’t get it. Why is the Death Knight deck more expensive? The prices of the other decks make sense (Paladin is cheapest with loads of Commons, Hunter has a lot of total cards granted and shares the price of Warlock.) But I don’t see any reason Death Knight should be almost 50% more.

All of them are offered for 500 rune$tone$ to me.

Prices in real money? Haven’t they been history for quite some time?

because until you give all your money to blizzard you will not win, you have to give it all, even sell the jewels you have in your house
