The EU Summer prelims will be played out over the 13th and 14th August 
2016. You can watch all the action on the Hearthstone Twitch Channel.
Here is the RDU EU Summer Prelims Aggro Shaman Deck he will be using to try and advance to Blizzcon. Remeber, tournament decks are not always the strongest ladder decks, but there is a lot you can learn from playing with these decks.
Aggro Shaman is one of the strongest ladder and tournament decks in the current META. It’s capable of winning vs any decks with it’s disgusting amount of burn that can ignore taunts and just go face for a finish.
Expect to see most players bring a list similar to this one. As well as some midrange Shaman.
