This Deck focuses on only defending 3 Idols and stall the game, until you have the economy to slowly kill your opponent Idols with direct damage.
The most useful scrolls to stall the game and build up resources, are Waking Stones, Sickening Fumes and Warding Stones.
Try to block damage with your Oblivion Seekers and make use of Heritage.
Sac all the direct damage Scrolls (Wicked being, Reaping Mask etc.) as you will need them later, try to increase your ressources/Scrolls in Hand while defending 3 rows.
Prepare to play at least 20-30 Minutes as this deck is very slow.
