Without Aether walker - I'd drop Teleport and go with Black Hole. I'd then switch Frost Nova with Blizzard - Frozen Solid and then maybe swap out Nemesis Bracer with Ancient Parthan Defenders or Ashnagarr's Blood Bracer. Mind you - the black hole set up is very slow as in you're not teleporting everywhere. Hence why you need Blizzard to freeze all the enemies so you can get around them and then cast black hole once archon is ready to capitalize on the Spellsteal rune.
If you want to use Teleport - I'd then go with Aether Walker and In-Geom combo. And still stick with Nemesis Bracers and the rest of your current ability setup. This setup is great for Speedruns.
