Using the Ob Nixilis deck of the "Duel Decks: Nissa vs. Ob Nixilis" as a start to build from i made this little annoying deck.

It uses nukes (like Doom Blade and Hideous End) and flying creatures (like Mindwrack Demonfoil icon, Desecration Demon and small ones Fetid Imp, Insatiable Harpy) to pressure the enemy.

A combo for this deck is the Wall of Limbs and lifegain (Gift of Orzhova, Child of Night, Tribute to Hunger), where lifegain is also a nice bonus to have when you dont draw Wall of Limbs.

You get a little draw with cards like Ob Nixilis Reignited and Read the Bones.

The monoblack makes Nightmare and Squelching Leeches pretty good.
