Hi, Sipiwi94 here!
I am currently playing on NA because I am #1 on EU. However, my collection is very limited on NA, so I am only able to play Egg Druid, Pirate Warrior, and Aggro Shaman. I don't find these decks very fun, so I tried to figure out if you could create a control or combo deck without needing a lot of legendaries. And here it comes!
EDIT: I just hit #1 legend with the deck.
The OTK Priest for the poor player
I haven't tested this list a lot, and it might be possible to improve it with epics or legendaries. But the list works very well between rank 5 and legend so far. I am convinced that epics and legendaries wouldn't improve this list.
The gameplan is to gain board control and stack health on one minion to threaten the huge buff combo kill. You have to be aware of single target removal, but sometimes you can't play around it. Against Reno decks that most of the time only use 1 single target removal you rarely play around it. You can check for it though by not buffing a minion with all you have at once.
You have to draw with this deck. Acolytes and clerics are your main draw tools. These are powerful in combination with Pyromancers and Circles.
Against aggro just forget all the above. You want to survive at all cost and you have a lot of different tools to do that.
I will update this guide further when I have played the deck more, if people find the decklist useful.
