Plague Bloom

As you cast this spell, choose a creature on the battlefield. For each creature that shares a name
or creature type with that creature, destroy those creatures. For each creature destroyed this way,
repeat this process.
Foolish exploration in biological technologies unearthed
the contagion. Spreading at breakneck speed, there
was little that could be done to mitigate the disaster.
