Yings dimensional rift can help her bring her back onto where her illusions are when knocked by torvalds ult.

Nullify can target ying illusions, which does nothing to benefit you, so make sure you know what nullify is aimed at before using it

The legendary damage for your attack is a good choice as the frontlines are for most slow moving and thus you can deal insane damage while counter their damage with you illusions (you can also use them to disrupt the beam of torvald)
