Card of Demise and Pot of Desires is the draw power of this deck.
The strategy of this deck getting at least 1 monster (more better if you got Stone Statue of the Aztecs because this card can deflecting double damage).
The Ancient One is a One Shot Kill, if the opponent hasn't conceded yet. I have recently been seeing all these "OTK" titled decks and wasn't sure what it meant, so I Googled it. Now I may be a noob for not knowing this, but thinking about these so called "one turn kill" decks just doesn't make any actual sense.
Killing your opponent on turn 5,6, or 7 for instance in one shot or with a certain You are killed from full in one turn.
In Hearthstone, that means a combination of cards which when playing in a turn deals 30 or more Damage.
This was an actual thing in Magic The Gathering back in the day with ridiculous combos that were banned in tournament play.
Cross Counter can doubling deflecting damage (like Stone Statue of the Aztecs effect).
Reverse Glasses, Mirror Wall, and Shrink is good to halving opponent monster(s) ATK.
Defence OTK Duel & Decklist : Stone Statue of the Aztecs Rise to Full Height D2 Shield set that 3 cards.
If your opponent attack your Stone Statue of the Aztecs, active Rise to Full Height and chain with D2 Shield, that will make Stone Statue of the Aztecs DEF become 8000.
