Shiv's ult can jump through McGinnis wall if he initiates it before the wall is up.

[Nildawenn]

If Shiv is in the air from his ult and you put up a wall between you and him as McGinnis, he will come through the wall.

This also happens with Yamato against McGinnis. Paradox can also switch places with McGinnis through her wall.
