  • The generated spells can be from any class, they are not restricted to Mage spells.
  • Spells that cost 7 or more mana will transform into 10-mana spells, but retain their original cost. E.g. Power of Creation might transform into an 8-mana Nagrand Slam.
  • Reducing the cost of the spells in your deck before using Deck of Lunacy (via effects like Incanter's Flow) makes Deck of Lunacy use the reduced cost, not the original cost, when calculating which spells to transform into. For example, a 7-cost spell would normally transform into a 10-cost spell, but if reduced to 6 mana before playing Deck of Lunacy, it will transform into a 9-cost spell instead. Therefore, it's usually more beneficial to play Deck of Lunacy before Incanter's Flow.


Deck of Lunacy is a powerful card when played early. In order to take advantage of its effect, it is a good idea to have as many spells in your deck as possible, since many spells upgraded by the Deck of Lunacy will summon minions themselves. Playing Deck of Lunacy followed by Incanter's Flow can be a great source of cheap but extremely powerful spells.

During early game, be sure to play it as soon as it's drawn, even if it's at the cost of losing tempo or sustaining some damage or both. It will soon redeem itself over the coming turns and give you an overall advantage.

While it can be devastating for your opponent if you find Deck of Lunacy in hand during mulligan or in early game, your deck should be competitive in itself as there can be a good possibility that you end up not drawing it and thereby losing the game.

In the Year of the Gryphon, the consistency and predictability of generated spells has greatly improved in Standard with all the Year of the Dragon spells, as well as many of the weaker spells from the Classic set, rotating out. This resulted in Deck of Lunacy giving powerful spells like Skull of Gul'dan, Libram of Hope and Nagrand Slam far more often, and it was suddenly thrust into prominence in the meta in the first two weeks of Forged in the Barrens. Following this, it was nerfed to cost 4 mana, up from 2, making it a greater tempo loss while preventing it from being played too early.
