The Bloom Warrior is the primary damage dealer of the team. Even without additional boosts, a 2-cost 3/4 unit offers excellent stats for a common unit. You can deploy them as-is, and they’ll perform well, especially if you can recover the boosts before they die.
However, their true strength lies in their ability to transform into 6-attack juggernauts with enough boosts, making them a terrifying threat to opponents. When paired with a Swift Potion, they can threaten a large area with a 6 attack (or 7 if enhanced by a Strength Potion), establishing them as a core threat of the faction.
The ideal strategy with Bloom Warriors involves summoning them, adding 3 boosts, and attacking with a 6 attack. Then, protect them with a Mind Warden. On the next turn, attack again with the boosted Bloom Warrior, even if it means taking on additional risk. After the attack, recover all the boosts, reducing the Bloom Warrior to a 1 attack unit. If your opponent hesitates to destroy it, you can once again load the unit with boosts, attack for 6, and then immediately use the boosts to create a potion. This pattern is incredibly powerful and forces opponents into difficult decisions.
Remember, Bloom Warriors are your primary threat throughout most of the game, so it’s wise to keep them in reserve until the later stages. Once you run out of Bloom Warriors, your threat range diminishes significantly.
