Imp Master is a rare neutral minion card, inducted into the Legacy set, formerly from the Classic set.

Previous availability

 * Regular Imp Master could also be obtained as a first-time reward for first time reaching Silver 10 and Gold 10 in Ranked mode from April 1, 2020 to March 25, 2021 (or as a reward of Climbing the Ranks (2/10) and (4/10) achievements).

Strategy
The mechanics of Imp Master work well when the only damage it takes is from its own ability, meaning this card is best paired with a Taunt. In a situation where your opponent does not have a lot of minions it can be very easy to overwhelm them. Paired with buffed damage such as that from Raid Leader or Stormwind Champion, Imp Master and its progeny can deal some serious damage to your opponent and their minions. Flesheating Ghoul and Knife Juggler also works very well with this card, especially if using your Imps to destroy enemy minions.

Healing abilities can be used to prolong the Imp Master's spawning indefinitely, such as the priest hero power Lesser Heal and the shaman totem Healing Totem. Health-boosting effects like Shattered Sun Cleric's battlecry will also extend this.

When facing the Imp Master, it's generally desirable to remove her as quickly as possible. Unless destroyed the same turn she is summoned, she will have already summoned a 1/1 Imp (making her a 1/4) by the time the opponent gets a chance to remove her.

If there is no room to summon an Imp, the damage still occurs.

Trivia

 * The artwork for this card comes from the World of Warcraft Trading Card Game "Heroes of Azeroth" series, for the card.
