This is a casual Vintage deck that forces opponents to draw and discard a great deal of cards and punishes them for it.
Font of Mythos and Howling Mine are the draw engine.
Hymn to Tourach and Mind Twist will cause the discard.
Library of Leng will allow me to skip discard as well as use Memory Jar and Ill-Gotten Gains without truly having to discard anything.
I have also included Memory Jar and Ill-Gotten Gains to allow a great deal of drawing or discard (with other, obvious benefits)
Liliana's Caress and Underworld Dreams are the pain cards that will cause the majority of life loss.
I have creature control with Lethal Vapors, Mutilate, and Killing Wave. I have also included Drain Life as a creature control or direct assault card.
Haunting Echoes will permanently deal with any creatures I control with the other creature control aspects.
Drain Life and Ivory Tower will allow me to gain life as the deck is ramping up.
Pithing Needle is there to protect the Lethal Vapors or to take care of any other bad vibes my opponent may conjure up.
Please provide any feedback you have. This is for a 1 on 1 casual deck.
