Spectral Matron

Whenever Spectral Matron enters the field, you can reveal one creature spell in your hand. If you do, create a token creature that's an exact copy of it.
Any creature created by Spectral Matron's effect, dies during the ending phase.
The ruination corrupted all those caught in its path.
The kind became cruel.
The brave became brutal.
Reason gave way to resentment.
