Hearthstone Standard Aggro Warlock Mulligan and Play Guide

To win with Standard Aggro Warlock in Hearthstone, secure a proactive 1-mana minion during the mulligan, spend all available mana across Turns 1 through 3 to build a wide board, and pivot all damage directly to the enemy hero by Turn 5.

Mulligan Strategy

An opening hand without an immediate play puts Aggro Warlock at an immediate disadvantage. Mulligans must strictly filter for low-cost board presence.

• Always keep: Any proactive 1-mana minion with solid baseline stats, such as 1/3 bodies or token generators.
• Keep with The Coin: If an active 1-drop is already in hand, keep a strong 2-drop and a 3-drop to guarantee a continuous curve.
• Keep against aggro mirrors: Low-cost Rush minions or targeted damage spells that remove opposing 1-health openers without stalling your board development.
• Always toss: Any card costing 4 mana or more, passive card draw, and situational removal spells that do not summon minions.

Curve Management and Life Tap Timing

Aggro Warlock runs a dense suite of 1-drop and 2-drop minions, causing cards in hand to deplete rapidly by Turn 4. Managing your hand through the Life Tap Hero Power requires strict discipline.

Using Life Tap during the first three turns surrenders tempo and delays board development. Only tap early if your hand completely lacks a playable minion on curve. Beginning on Turn 4, tap when you have two unspent mana after deploying your primary minion threats.

Self-inflicted damage must be weighed against opposing burst potential. Against aggressive classes like Hunter, Demon Hunter, or burn-focused Mage decks, preserve enough health to survive a full turn of direct spell or weapon damage before tapping.

When to Trade vs. Attack the Enemy Hero

Combat shifts from controlling early opposing drops to pushing lethal damage as the game progresses into the mid-turns.

Do not initiate 1-for-1 trades against minions that cannot eliminate your high-value attackers on the opponent's upcoming turn. If an opposing utility minion poses no immediate combat threat, direct your attacks at the enemy hero and force the opponent to spend their mana answering your board.

Combat Sequencing and Sweeper Management

Sequence your board attacks to minimize losses from reactive secrets and triggered effects:

1. Attack with non-essential minions first: Test for enemy secrets, Deathrattle summons, or damage triggers with low-stat tokens before committing your primary attackers.
2. Account for positional auras: If a minion provides adjacent attack buffs, place new units where they will inherit those stat bonuses as older attackers die during trades.
3. Stagger secondary minion waves against area-of-effect spells: If your active battlefield already threatens lethal damage within two turns, hold additional minions in hand. Staggering your resources ensures you can rebuild the board immediately if the opponent spends their turn casting a board wipe.
