Maeve can down you in just a few knives. Get Haven and Life Rip for sustain, and save In Pursuit for securing the kill. Discovery will be the best choice to keep her in check, making sure she doesn't flank from behind and poke the backlines.
Always try to keep the Torvald occupied. Your Totemic Ward counters Nullify and his Ultimate, and chances are, the Torvald will cast his ultimate as you and your allies are in range of your Totem.
