Transformed minions[]



  • Transforms another random minion into either a 1/1 Squirrel or a 5/5 Devilsaur. Both are Beasts.
  • Note that transformations are permanent, and cannot be undone. Returning a transformed minion to the owner's hand will not revert it to its original form.
  • The target for this minion's Battlecry is chosen at random. However, it will not target Overspark himself.
  • The result of the Battlecry is also determined at random.


Tinkmaster Overspark is a very risky card. This card is best used in a situation where the controlling player has little to lose, or the opponent has a lot to lose.

An important limitation is that Overspark will not be selected as the target for his own ability. If played with only a single minion on the board (even if it is Stealthed), that minion is guaranteed to be chosen as the target.

Overspark can be useful when played on a board filled only with low-stat friendly minions without abilities, such as 1/1 minions. This provides a 50% chance of upgrading one of these minions to a 5/5, serving as a useful boon. However, be aware that this will also change the minion's type to Beast, making it less desirable for type-synergy such as Murloc play, for example.

Overspark is useful against extremely powerful minions with useful card text or enchantments such as Malygos or Ysera (and other strong minions not susceptible to Big Game Hunter). Even if the result is still a substantial 5/5 Devilsaur, it is better than things such as high health or devastating abilities. Note that the main effect of this ability is to remove all card text and enchantments, effectively Silencing the target minion; the precise stats produced cannot be predicted, and are often of smaller consequence.

The random targeting of Overspark's Battlecry can make it effective against Stealthed and "Elusive" minions, such as Shade of Naxxramas or Spectral Knight. Even if the result is a 5/5 Devilsaur, by transforming the minion the Stealth/Elusive ability will be removed, allowing the player to then specifically target it with another effect.

Overspark's Battlecry can be used as a (somewhat unreliable) tech card, since his Transform effect "deletes" a minion from the list of destroyed minions, preventing them from being brought back with Resurrection effects. This prevents cards like Doomcaller, N'Zoth, Feugen/Stalagg, Bloodreaver Gul'dan, and Witching Hour from reviving key minions and significantly reduce its effect.

Tinkmaster Overspark is a level 57 gnomish engineering trainer located in Tinker Town in the dwarf city of Wowpedia. He holds the title "Chief Architect of Gnomish Engineering".
"I am Tinkmaster Overspark, and I am the chief architect for modern gnomish engineering principles in the world today. It is my job to ensure that the power of invention continues to shine brightest from our arclight spanners than anywhere else!
Also, if you happen to know a good schematic for radiation elimination, we just so happen to be in the market for one right about now..." - Tinkmaster Overspark


  • The artwork for this card comes from the World of Warcraft Trading Card Game "Fires of Outland" series, for the card Tinkmaster Overspark.
  • Prior to release, Tinkmaster's Battlecry allowed the summoning player to select its target, although the resulting minion was still determined at random. Because of this, during the game's beta Tinkmaster was widely considered a very powerful card and became prevalent in high-ranking decks, with many players considering it a mandatory inclusion. As a result, Tinkmaster was nerfed by the developers, with his Battlecry now choosing a target at random. Videos such as this one commemorate the rapid devaluation that took place following the change, with many players immediately disenchanting the card.
  • His summoning quote may be a reference to Bullwinkle J. Moose in The Rocky and Bullwinkle Show, where Bullwinkle tries to pull out an animal out of his hat for the fifth time and says "This time for sure!", before pulling Rocky out of it.
  • Tinkmaster Overspark's entrance music is taken from Battle for Gnomeregan. This sting is shared with Gelbin Mekkatorque, Millhouse Manastorm, Nat Pagle, and Captain Greenskin.
