Hearthpwn

For starters, this deck is my own invention and I don't have the patience and time to try and grind the ladder with it and search for weak spots. BUT IT'S HELLA FUN!

What you basically try, is to get some reasonable strong minions on the field that will not be killed in the next turn. KNIFE JUGGLER is really nice to open with, with the thought of not getting it killed soon. I usually save them for when I get MUSTER FOR BATTLE and pray to rng something good comes out of it (always keep a back-up plan in mind though).

You try to use  SEAL OF CHAMPIONS to make up trades for either bigger minions or when you think you can pull of lethal with the minion next turn.

You never use BLESSED CHAMPION to kill a minion unless you are 99% certain that it will make you survive a little bit longer and you're close to winning.

You want to hold on to your blessings for when you can achieve lethal damage in combination with BLESSED CHAMPION. But ofcourse when something has to die, make it die.

Keep the ECHOING OOZE reserved to play along with a blessing that would do really good in the particular situation.

For the mulligan you want to aim for KNIFE JUGGLER and MUSTER FOR BATTLE. SHIELDED MINIBOT is also keeps ofcourse. you just want some cheap minions in that starting hand.
you do not want to have any blessings in your starting hand.

Replacable:

Tirion Fordring - Ravenholdt assasin - war golem - force tank max
Bolvar Fordragon - Ravenholdt assasin - war golem - force tank max
seals of champion can be replaced by sword of justice and, if you feel like it's needed,                                                                                                                     another blessed champion
Belchers - sunwalkers

Now go ahead and thirty to zero some people in one turn.
