Can i use Audition to create EDM mixes?

You've asked two different things here, and the answer to each is different. In the thread title, you've said 'can I create an EDM mix?' and the answer to that is clearly yes, you can - using Multitrack view that is relatively easy; you place the clips you want onto a track, and you can either butt them up or cross-fade them to your heart's content. You can also EQ them, alter the pitch, apply individual effects to each clip, etc - no problem. But...

The creation of tracks in the first place, though, is another matter altogether. Since Audition is fundamentally an editor, it's not really designed for music origination as such - no MIDI capability, and it doesn't support VSTi instrument plugins. Almost certainly a better approach would be to use some music creation software - like Reaper, for instance (although there are a lot of other options), and then use Audition to finish the process off, as I described above.

HTH.
