Kazakus : ALWAYS KEEP, he will be important in each matchup, the only moment when you don't keep him is when the rest of your hand has no reactive spell and you want to increase your chances to draw more impactful early cards

Reno Jackson : ALWAYS KEEP, don't even think about shipping him.

Mistress of Mixtures : Life gain and trades with early minions

Mortal Coil : Depends on the rest of the hand, keep it if you already have Reno, Kazakus, Doomsayer or Mistress of Mixtures

Acidic Swamp Ooze : Destroys Warrior weapons, no matter what variant.

Doomsayer : Play it turns 2 or 3, they can kill him usually with weapons+minions, worst case scenario he's 7 life gain

Shadow Bolt : Kills all relevant minions and gain tempo

Imp Gang Boss (Only with coin) : Trades pretty well and leaves a body to contest 1 health minions, a bit slow without coin can be kept if the rest of the hand is good enough
