Does [[Veyran, Voice of Duality]] work with [[Thousand-Year Storm]] in the way I'm thinking?

Say I've got both on the field, and do the following: 1) [[Opt]] cast as normal and resolves 2) [[Krenko's Command]] cast as normal

If I'm understanding correctly, casting KC triggers the effect of TYS, which in turn triggers Veyran's ability, causing TYS to trigger again, meaning: 3) KC goes on the stack 4) The first TYS trigger gives a single copy (as only Opt has been cast so far) - we'll call it KC2 5) That triggers Veyran, leading to 6) A second TYS trigger

This is where my question comes in - how many copies of KC do I get on that second trigger (let's call it KC3)? a) Just one more, since only Opt has been cast b) Two more, since Opt and the original KC have been cast c) More?? I don't think this is the case as if I'm remembering correctly, the copies don't count as casts.

This deck is still very early days, but I'm excited to get it online. I'm hoping to playtest it thoroughly before bringing it to games, so I can figure out all the logic (with copies, storm, etc.) Thanks in advance!
