This deck is a value/control deck based around lands.The Gitrog Monster lets you draw multiple cards a turn, whilst groundskeeper lets you get the sacrificed lands back. Tireless Tracker helps you get the most value out of each of your land drops. Mindwrack Demon is a great finisher whilst also filling the graveyard for seasons past and Gitrog Monster. Removal spells and hand disruption help sure up the early game.

EDIT: Removed 3x Mindwrack Demon and added 2x Grasp of Darkness and 1x To the Slaughter. Removed 2x Transgress the mind, added 2x Duress. I removed the demons because it was more difficult than I thought to turn on delirium and I was losing a lot of life from them. More early removal was added to help get to late game.
