MANAHIVE

Equivalent cards to Screeching Bat (Creature — Bat, Black, flying, transforms for a cost):
1. Screeching Bat – original card.
2. Shrieking Bat – this is the transformed side of Screeching Bat, but no other black Bat creatures specifically transform for a cost.

Closest equivalents with similar attributes:

• Heir of Falkenrath (Creature – Vampire, black, flying, transforms by discarding a card)
• Duskwatch Recruiter (not black, but transforms for a cost)

Reason: There are no other black Bat creatures that transform at a cost. Only Screeching Bat fits all criteria. Closest alternatives may transform differently, but not with the same effect or cost.
