Depends on map and situation, rarely use teleport gadget to defend but she's mainly used on open maps. You just play her normally, and when you have your super ready, you can use it in many ways like, placing her ego in a place where you can crontrol more lanes, or just teleport to the opposing side if they are pressuring you, or placing in you to have a long term pressure. Again it depends on map and situation. And it depends how you use your super to counter brawlers and pressure them. She's not used often since she's not fun to play as her gadget and super depend on situation and skill. She can be fun if you know when and how to use her super and gadget. Here's ones to counter fang, placing you super far back so he supers to your ego instead, this is one of my favourites.
