  • Demonfuse cannot be used on the Lord Jaraxxus hero. However, it can be used on a Lord Jaraxxus minion.[1]
  • If Demonfuse is cast by an effect such as Yogg-Saron and has no Demon to target, the second part of the spell will not activate, and the opponent will not gain a Mana Crystal.[2]


This is a hard to use Demon buff card, similar to Demonheart and Demonfire. The buff itself is a tempo increase (+3/+3 for 2 mana), however the card's secondary effect makes this an overall tempo loss since for the remainder of the early game your opponent will have one more mana than you. Best use is not for the early game (the earlier you play this the more advantage you give to your opponent) but as a mid-late game push for burst damage for a tempo demon warlock deck; however, this purpose can just as easily be fulfilled by a burst damage spell like Darkbomb or Soulfire, which do not have downsides that make them undesirable to play earlier in the game.
