Hearthpwn

my fav deck in wild are control/value mage and control priest, Im doing okayish with both

in standard my fav deck (and the only one i play atm) is miracle

Malygos Garden Rogue in Wild: i love to play reactively with bursts - yet vulnerable to Aggro without godly draw.

Eggro Druid in both modes: growing up your whole board is refreshing - yet vulnerable to Tempo/Control.

I have been having fun and winning with this deck.

then this ridiculous deck lol, I have won with it a good amount and it's stupid fun for me. 

LYRA PRIEST EZ

Decks i'm having most fun with right now :) 

Evolve shaman. Bonus points: it really irks all those backpipe retentive's who complain about RNG :)

Lyra Priest is really fun

Honestly a very fun deck right now is Silence Priest it's also quite strong

Evolve/Devolve Shaman, Quest Shaman

Discovery Warrior

Yogg Secret Hunter

Casino Priest

I am playing Medivh Control Priest mostly and have a lot of success and fun with it. Lots of crazy turns with Lyra the Sunshard. One could probably cut the whole Medivh, the Guardian + Free From Amber package and add an Elise the Trailblazer and maybe a Burgly Bully. Try it out and see for yourself!

Decklist: 

You can't really say ''this is a fun deck to play''... Players have different opinions on what they find fun, some people find it fun to play RNG cards like Yogg, others think that the most fun you can have in the game is trying to be super competitive. (and so on)      :P
