- Cruel Firebloom can be soul summoned with 100 soul gems or found in Core set packs.
- Cruel Firebloom is included in the Brynjolf's Heist theme deck.
Cruel Firebloom deals fairly high damage, more than even Lightning Bolt, making it a potent removal option. Its cost of 0 makes it playable at any time, allowing it to be a constant threat. However, it is hindered by requiring a creature to sacrifice and being impossible to aim, restricting its effectiveness against multiple enemy creatures and putting you at a disadvantage in cards. Ideally, it should be used to sacrifice a cheap creature with a Last Gasp ability to offset the loss of card advantage.
