Reply to 2 midi fighters, Deckalized mapping, and the m-audio x-session mixer

I just recently bought the x-session mixer which is a midi USB mixer, and i was just wondering if that mixer plus 2 midi fighters would work as a solid beginners DJ kit. O, and I'll also be buying the audio 2 for my sound card. So i got that covered.

Also, because the mixer is midi will that interfere with the midi fighters and the deakalized mapping?

Thanks! Im excited to finally start getting some dj gear to start practicing with!
