The deck has card draw and plenty of board removal options and healing to last until late game.
Stay alive until you can meet the combo conditions.
The combo is Chun double battlecry for 60 damage in one turn.
The way it works is you use lighting bloom to activate the courrpted waters Hero power.
You can also use farsight to reduce the cost of the combo pieces by 3 which also allows the double battlecry.
King Pharos is a good option for this deck and so is Naomi
The legendary weapon would fit good here too.
You can also double battle cry on Thogg for fun.
It doesn't really have to many weaknesses but aggro can be a prob Make use of the the double battlecry for healing and spell selection mid game.
The deck has room for tweaking Im sure. And Im still playing it but the win rate is about 50/50.
If this deck is optimized more I think It could be pretty unstoppable.
The combo is 3 cards so the other 27 are really just compliment the OTK and speed it up.
Galakrond is also an option for this deck but watch out to not delete the battlecry hero power by accident because that is a little counter productive.
edit: Circus medic is just very good in this deck can give mid and late game stability if you need healing damage even a finisher sometimes if the opponent is low on health.
I tried Diligent Notetaker in this deck bc it can copy spells. One issue this deck has is the warlock card Tickatus (currupt remove the top 5 cards of your opp deck). I had tried to copy a combo piece with dildent and substitute it for the destroyed card but that does not work.
King Pharos is a second win condition for this deck if timed right other wise use it to lure opposing AOE board clears.
That's it for now.
