...well not exactly 100%, but I hovered between 85% and 90% winrate from rank 20 to rank 5 with this deck. Going for legend over the weekend. It's not the most competitive deck, but it's not bad at all and can surely take down your opponent by surprise.

Strategy

The general idea behind this deck is to play Call to Arms to summon one or two Mana Addicts and protect them with Righteous Protector and Wax Elemental. Since these 3 minions are the only targets you have you are very likely to get a Mana Addict off and protect it with 2 taunt minions. The turn after you idealy have some cheap spells like Blessing of Might to buff your Mana Addict and then try to go for Windfury with Adaptation. If you hit the right cards you can easily OTK people as early as turn 3!

"What a rush!"

If you can't kill people early on with your combo, this deck can still fight for the board pretty well with all the Divine Shields and buffs. Sunkeeper Tarim is a great midrange card that can be used to clear a board in your favor if you hit his battlecry on Righteous Protector and Wax Elemental.

Given the fact that this deck has insane highroll potential in the early game you can win almost any matchup. On average though this deck performs rather bad against Warlock of course due to their efficient board clears and Voidlord. Aggressive Paladin decks and Zoo Warlock are a problem as well, because they are much better at fighting for the board early on. This deck shines against slower decks like Druid and most Priest versions, even though Duskbreaker is a thing.

Card Choices

Blessing of Wisdom:
There isn't much room for flexibility in this deck I think, but this is one of the cards that we can discuss. I chose this card over Divine Strenght as a cheap buff, because I think that card draw is fairly important for this deck. Apart from Divine Favor which can be dead in some matchups, this card not only provides good card draw early on if you put it on a Divine Shield minions, but it can also be used as a semi defensive tool if you cast it on a big enemy minion. Plus it's fantastic in combination with Windfury from Adaptation.
Divine Strenght on the other hand not only gives you more damage, but it also puts your Mana Addicts out of reach from popular AoE such as Duskbreaker and Hellfire. Both are good, but I decided to go with Blessing of Wisdom for now.

Chillblade Champion:
This is yet another card that is not in the 26 key cards. It is a very flexible card though. It can be used as a removal if necessary and also provides some more reach especially if you cast some buffs on it. In theory this can give you access to up to 20 damage of burst from hand if you hit Windfury on Adaptation. It also has Lifesteal so it can give you back huge chunks of health in matchups like Secret Mage.
I've been swapping this card with Consecration lately because I faced more Murloc Paladin on ladder. Another card that can be played here is Leeroy Jenkins because of the great burst potential.

Lynessa Sunsorrow:
This card is one of the most important cards in the decks. If you are a fan of her, here you go. This deck runs a total of 12 buffs including very strong ones like Spikeridged Steed. Sometimes the games go a little bit longer than you would like and then Lynessa Sunsorrow gives you a last resort to take the win. You can easily get here off with 8-9 buffs in the lategame including multiple Blessing of Kings and make a huge minion. Most opponents have a hard time dealing with her, especially if you get that shroud effect off Adaptation. Just make sure to watch out for Spellbreaker.

Conclusion

Overall I think this is a super fun deck and something refreshing for now. It's also not terrible at all, if you are between the ranks 15 to 5 this can easily achieve a high winrate. Most matchups are very winnable, even against Warlock you have a good chance of winning if you just go for the aggressive Mana Addict. Play around AoE in your favor and you will have a good time playing this.
