Modern U/B control deck featuring the interaction between Paradox Haze and Neverending Torment, with other upkeep activated cards, like Venser's Journal to gain life and stay alive and increase the number of cards in hand.
Explanation of other (Nonland) cards:
-
Ancestral Vision
: One mana for 3 cards, get cards faster after using Paradox haze.
-Damnation: There is one creature in this deck and I don't want to splash white.
-Dismember: Turn one removal that ignores indestructible. Good times.
-Dissolve: Counter a spell, then scry. Pretty good in most situations.
-Fatal Push: Removal for one, very situational.
-Go for the Throat: Removal for two, picks up Fatal Push's slack
-Increasing Ambition: Tutor, then tutor more.
-Laboratory Maniac: Because Mind Unbound is incredibly dangerous.
-Mana Leak: Because I'm pretty sure Counterspell isn't modern legal.
-Mind Unbound: Advantage. So much advantage. Warning: You may draw your entire deck from this one card.
-Neverending Torment: Main win condition. Just exile their entire deck. What are they going to do about it?
-Never / Return: Removal for three, deals with pesky planeswalkers, then summons meatshields.
-Paradox Haze: So I heard you like upkeep effects.
-Venser's Journal: Ditch your maximum hand size, and gain life for taking advantage of that effect. Pairs well with Paradox haze. Or 2. Or all of them.
