Elesh Norn Mother of Machines stops Lys Alana Huntmaster from creating Elf Warriors. I had Lys Alana Huntmaster out, which lets me create a elf warrior when i CAST an elf card. The opponent had Elesh Norn Mother of Machines out and that card stopped Lys Alana from creating the elf warriors. Lys Alana Huntmaster clearly states "cast". This is not an ETB effect and thus it should not be stopped by Elesh Norn Mother of Machines.
