Aggressive priest decks are usually difficult to build, largely because they are a very reactive class whose strengths lie in being able to respond, rather than initate. However, with the use of both Dragon and Nerubian Egg, this deck allows the Priest to use its strong buff cards to its advantage, such as Velen's Chosen and Power Word: Shield. I have had a lot of success with this build around rank 7-12, it's surprising how effective this deck can be.

Key Cards and Synergies:

Nerubian Eggs & Dragon Eggs:Your opponent will probably ignore these cards when you place them down, but with 7 activators (2 sergeants/2 argus/1 dark iron dwarf/2 velen's chosen) in your deck you will be able to make them suffer for it with considerable reliability. Dragon Egg is interesting in the sense that you want it to have lots of health, so unlike Nerubian, it's also a great target for Power Word: Shield.

Thoughtsteals / Azure Drakes / Northshire Clerics:
Priests often have trouble sustaining draw power in aggressive builds, but the combination of these cards means that, provided you play intelligently, you will rarely ever be out of cards.

Holy Novas:
With 2 Velen's Chosen and 2 Drakes, this is your only spell dmg outside of thoughtsteal shenanigans, but its the best card to benefit from it given its devastating AoE effect. Perhaps the greatest thing however, is that with your eggs and other sticky minions on board, you will often be able to take advantage of Clerics + Holy Nova combos, netting you big draws more often than you might think.

Annoy-o-Trons & Defenders of Argus:
This deck functions well against other aggro decks, given the sticky eggs, and the scary taunts you can put up in the process. Both of these cards prevent your opponent just mindlessly hitting face and overwhelming you.

Knife Juggler:
Knife Juggler is good in most aggro decks, but its applications here are more intriguing than usual. It works well with the sticky haunted creepers as you'd expect, but also has additional synergy with the eggs that summon minions.
