MANAHIVE

Cards equivalent to Homicidal Brute (color: Red, creature with a transformation ability tied to attacking):
1. Village Ironsmith // Ironfang – Red, transforms based on conditions related to attacking/blocking.
2. Reckless Waif // Merciless Predator – Red, transforms if no spells were cast.
3. Vildin-Pack Outcast // Dronepack Kindred – Red, transforms based on spells cast.
4. Homicidal Brute // Tormented Pariah – The original requested card.

Reason: Few Red creatures transform for not attacking, but these Red double-faced creatures transform under similar turn-based conditions.
