Imp Zoo Warlock Deck Strategy

During the early turns, you should use your cheap minions like Flame Imp, Flustered Librarian, and Wicked Shipment to quickly populate the board, taking value trades as necessary. This can swiftly be followed by Vile Library and Fiendish Circle.

When using Vile Library, you should consider when and which minions you use it on very carefully. Generally speaking, it is best to use it as soon as possible as it has a 2-turn cooldown period before it can be used again. However, if you have a Fiendish Circle in hand, for example, it can be worth waiting a turn as you will again an additional 4/4 in stats from its use. When choosing a target, as a rule of thumb you should target a minion that is able to attack in the same turn, effectively giving 'Charge' to the buff as it can be used immidiately. However, if you find yourself in a tough spot, do not hesitate to use it on a minion summoned in the same turn, especially a Voidwalker if you need to secure control of the board.

Throughout the game, you should look to take value trades into enemy minions while pushing as much remaining damage to face as possible to pressure your opponent. This method of keeping your minions alive will maximise the value of your Vile Library's and Shady Bartender's buffs for maximum value and burst damage. If your opponent is able to clear your board, you can make full use of Imp King Rafaam to repopulate your board as a last stand to close out the game.

Against Aggro you should heavily prioritise value trades to stay in control of the board as it is unlikely you opponent will have many comeback tools. Through aggressive board control you should be able to slowly chip away at your opponent's Health to close out the game.

Against Control you should prioritise attacking your opponent directly much more highly, only trading when absolutely necessary to protect high-attack minions like Flustered Librarian. Once your board reaches a modest strength, generally around 4 or 5 minions, you should replenish your cards if possible, making use of Impending Catastrophe and Life Tap to ensure you have enough minions to repopulate the board if your opponent is able to clear it.
