Like I said on the other RNG thread: From hundrets of cards in the PTR there are 35 cards with random abilities and I believe 10 cards with create, of which 5 are the runestones which are basically the same card. Out of the random crads, most are from the reveal archetype, in which you often times reveal cards from your opponents deck, so it makes sense to not show you their whole deck. Also it seems to encourage special/artifact decks so you can put some consistency in your reveals. Most of the other random cards are ongoin effects, like do one damage on turn end or when something dies, which makes sense to be random both from a technincal and a gameplay standpoint to reduce interruptions of the game.
Of course you can criticise the new design of reveal or say that you want to do every little point of damage yourself, but calling the game a "random solitaire with a minimum of brain effort" is not justified in my opinion. Especially with the new deck building your brain is challanged more than ever before to make a good deck (unless you netdeck of course).
