No, that's really not how it works. Diablo effectively has no hero power for the first 3 turns. This means that by the time you face the whole lobby, you are statistically going to be weaker than 90% of the lobby, since at every decent rank the only heroes (with a few exceptions) that see significant amounts of play are the ones who have hero powers that give them early tempo advantage.
But let's say you had a lucky game, got some really good shops and are very strong for the current turn. Great, now you get all the treasures! ... right? Wrong. Since the only thing that matters is not whether or not you win the game but whether or not the 3/3 demon you summon survives, you could literally win all your games and get zero treasure if you're exceedingly unlucky. In practice it means you'll usually get 4-6 treasures.
But lets say you got very lucky and have a full hand of treasures. Surely those will really help you cement a victory, right? Well no, again, not how it works. The treasures are relatively powerful if you use them on turn 5, but once it gets to turn 8 - which is when you should be using them, as you rightly point out - they're terrible. Deal 1 damage to 3 random enemy minions. Give a friendly minion +2/+2. That's barely even impactful at all by turn 8. And none of them are even permanent, they're all just single fight treasures. But hey, we had a full hand of treasures, at least we can guarantee we win most of the fights again and get another full hand of treasures. ... right? Nope. Remember the whole issue of it being possible to win the game and yet still get no treasure? Well, the odds of that happening just doubled from last time. A 3/3 on turn 4 has a decent chance to survive a hit from a small minion, but by turn 8, pretty much everything on the enemy board is going to have 6 or more attack, and they often have enough divine shields and deathrattles and stuff that your 6/6 demon will have to attack, and that pretty much guarantees that it dies. And that problem just gets worse the longer the game lasts, even if you're the strongest player in the lobby, your odds of getting a treasure just keep getting lower. I've had games where I won literally every fight on turn 8, and got ZERO treasures.
And that's not even mentioning that as the game goes on, fewer opponents remain, so your odds of getting treasures get even lower (since you don't fight against ghosts), while your opponents' odds remain the same. In other words they mostly have good hero powers that they've been using all game long, while you have a bad one that just keeps getting worse and worse the longer the game goes on.
I could go on, but this is getting long enough. Diablo is terrible, and very unfun, since you either highroll or you just get eighth. And even when you highroll, you're not nearly as powerful as other highroll heroes are, and hsreplay data supports that, Diablo has a terrible winrate.

Day one gold craft for the art alone.

I can't believe the comeback this card has made.

I'm honestly there and I only do dailies/weeklies, as well as a handful of times spent really playing to reach diamond each season. Of course this is after all of the concessions to the system Blizzard made when we rain felfire over it.

So I can dust my normal Edwin for full value then craft him in gold for rotation? Nice.

It seems like you can't complete certain quests in friendly matches against friends. For example the "play 3 games with x, y, and z class" triggered and completed but not the ones like "play 25 minions" or the new "play 50 cards under 3 cost". Was this intended? I'm fairly certain it worked a few days ago but I've been out of the Hearthstone loop. So I'm not even sure if this is a bug or removed feature.

Watch this be the week I get the tavern brawl quest.

Since I have a golden Lurker, this change is great because now I can actually use him!

Now this is theorycrafting at it's finest.

Are ranked seasons still just one month or are they longer now? I'm not excited to be bumped to essentially Rank 50 every month.

Warlock deserves one good class card for once.
