I just dont think that 2 strength is going to be enough to make the otherwise stellar Blades ability overly effective (unless you pair it with some crazy support cards and additional resist)

Infect commanders generally revolve around proliferate or poison counters directly, or combat to allow for creatures with infect to attack the opponent directly, oftentimes finding ways around potential blockers

This is certainly not generally considered a great result

Saying "I'm turning your creature into a Fish" rolls off the tongue way easier than struggling to say Ichthyomorphosis

On one hand, this is definitely a major downgrade to a card that could otherwise deal 8 Poison Counters
