When combining the Virulent Strain challenge with In the Lab, must you add the two In the Lab Virulent Strain cards?
The designer answered this in 2016.

By the strict rules yes: the two new Epidemic cards are shuffled in with the other Virulent Strain cards at setup. They are not required to play, though, and players can leave out any card they dislike.
