Cards replaced for the mini-set cards are 2x Stonehearth Vindicator and 1x Belessing of Authority. Had a winrate of 65% over 130 games on EU this season including playing it to legend. Star of the deck is ofc the Watchpost. 

Mulligan: A. Troggs, Banerman, Jewel Kit and Righteous Protector. Watch Post against caster classes including Rogue

                 B. Buffs if Trogg, Samuro if against suspected aggro and Vindicator if playing original version. 

Ivus is mostly used as removal tool, do not play until turn 5 as earliest.

Be careful with Trogg so you don't get board locked. But a board of Troggs and a Watchpost is a game winner though.

Don't play two Watchposts at the same time against priest cause of their mass silence. When they silence the first it can now attack and you can play a second one.

Bad matchups are Aggro Druid and Quest Rogue. Everything else is favoured or heavily favoured .

It still works great after the release of the mini-set. I'm 11-2 so far with it in EU legend. Check it out when I play it live at twitch.tv/diapsalma
