Creatures:
3 Shadowmage Infiltrator : Great card drawing.
3 Stalking Assassin : Reusable creature control, and powerful in multiples.
3 Mundungu : Reusable counterspelling, and at least deals some damage.

Other:
3 Unfulfilled Desires : Another great card drawer.
2 Breathstealer’s Crypt : Since this deck uses so little creatures, this card will wittle the opponents life down.
4 Recoil : Great control in late game, when your opponent has a high chance of discarding the bounced card.
4 Essence Vortex : At worst, its some good damage, and at best, its creature destruction.
4 Undermine : A counterspell that also deals damage.
3 Diabolic Vision : Good for getting me the card I need.
3 Sealed Fate : Gets rid of a card, that might be key, and can screw your opponents topdecks for a number of turns.
4 Barrin’s Spite : An edict and a bounce, and you get to choose the two creatures.
