Saturation.
But if we limit the signal at the grid of the output tube so as to keep the tube operating only in the "most linear part of the operating curve" (the definition of Class A) then it won't matter.
If we drive the output tube outside of the "most linear part" then we would want the positive half wave to move the tube toward saturation but be sure the drive stage can handle the low input impedance of driving the tube into grid current.
A 3 stage amp with the speaker connection inverted or a 2 stage amp with both the source signal and the speaker connection inverted.
But again, operating the tube outside the "most linear part of the operating curve" is throwing out the baby with the bath water.
