Strain Bravo: [Neuropathic pain] 
​Virulence: 8.5/10
​Pathology: A highly oppressive, symmetrical punisher. This strain attacks the host's central nervous system, turning their natural survival instincts against them. When the host attempts to draw cards, tap mana, or cast efficient spells, the pathogen triggers agonizing feedback loops (Roiling Vortex, Manabarbs, Spellshock).

Neurotoxin

Strain Delta - [Staphylococcus aureus]
Virulence: 7.5/10
Pathology: A hyper-aggressive, rapidly replicating bacterial colony. It generates massive horizontal board presence through continuous token generation and exponential anthem effects (Shared Animosity).

Bacteria

​Strain Foxtrot: [pneumonia]
Virulenance: 7.5/10 
Pathology: The newest addition to the armory. This organism operates via extreme cellular filtration (the "Explore" mechanic). Every combat cycle, the organism rapidly sequences its own DNA—either drawing vital lands to flood the board or permanently mutating its host bodies with +1/+1 counters

pulmonary edema 

Strain Charlie - [Toxoplasma gondii]
Virulence: 8/10
​Pathology: Arguably the most insidious organism in the lab. It exhibits aggressive mimicry and neurological attacks, presenting itself to hosts as a symbiotic "Group Hug" organism. In truth, it feeds on opponents' resources, lowering their threat assessment and immune responses until the strain becomes lethal.

Phantasmagoria

Strain Alpha- [Glioblastoma]
Virulence: 9/10
Pathology: This is a localized, uncounterable biological timer. It bypasses normal combat-damage routes, directly injecting the host with toxic material (Poison counters). Once a single spore enters the bloodstream, the organism triggers unchecked cellular proliferation (Roaming Throne, Inexorable Tide), multiplying the toxicity exponentially.

Cancer

​Strain Echo - [Mucormycosis]
Virulenance: 6.5/10
Pathology: A highly resilient fungal overgrowth. It possessed excellent resource-conversion metrics but a lethargic incubation period. It required 4 to 6 replication cycles to achieve lethality—too slow for the current meta-environment.
