The goal of this deck is to play as much as 3 Zerek's Cloning Gallery, thanks to Cleric of Scales on Shadow Visions.
The rest of the deck is a package made of tempo mid Dragons cards, providing value and AOE.
Some minions have synergy with the Zerek's Cloning Gallery, and the Spirit of the Dead, having taunt and death rattle.
Finally, Hakkar, the Soulflayer will punish combo decks.
Also, there is a very nice combo with him and the Cleric of Scales: it allows to remove your Corrupted Blood. Unfortunately, this combo doesn't work because the "discover" effect is still a "draw" afterwards (thanks Kuresha for spotting that).
Very fun deck to play !
