Hearthpwn

I'm only playing Reno Mage, and I easily get past rank 5 (already am from 2 days ago). It's extremely viable, you don't have to go cancer aggro or priest to climb up.

I've played HS since beta until recently. Stopped around November and tried MTGA, as it was the 1st card game that got me into this "card game universe". The way they handle monetization is years ahead of Hearthstone. Definitely still some changes are required, as nothing's perfect, but what would make me get back in HS is basically what MTGA offers us :

Give us a better way to grind in-game currencies

The HS system's completely obsolete compared to MTGA. Grinding 30 wins for 100G, and a daily quest averaging 40-80g depending which quest you get. Give us a better way to grind the game without having to pay enormous amounts of money. Literally look at MTGA : 

• 15 Daily Wins which each of them gives you different rewards (cards, gold)
• 15 Weekly Wins which gives you packs at each 5 wins.
• Daily Quests
• Competitive Constructed Mode in which you bring your own deck and gives you rewards at the end depending on how many wins you've got with a max of 3 losses. (This honestly is really what I would like to see in HS. The current ranked system isn't rewarding at all.)

Let's be honest here, high-end streamers that are handing away 1k$ to blizzard each expansions can't even get all of the legendaries/epics in a single set in those packs. How do you expect your "normal" community to be able to have those cards if giving you 1k ain't enough? 

Blizzard has made changes over the past few years when an expansion launches (logging-in legendary, packs, quests) which is great, but still, the daily basis grind still needs some love.

I've played this deck on ladder the past few days. Went from 11 to 7 pretty easily I'd say (played mostly against big spells priest, a couple tempo rogues/warlock). Didn't track stats though, but it's pulling good numbers.

Give it some time and practice with it, it's a really good control deck in the current meta. 

I can kinda relate to this since I was a free to player but the core set of mage is one of the best for control and you can have decent success just crafting 2x doom sayers. Normally tough in card games control decks are generally the most expensive ones
