As above. In your standard Rule of Three tournament you can have nine Talos, but only three units.
In their case I think it works to their benefit. Nothing like being able to move, advance, fire a pot shot haywire volley, then Fire and Fade yourself with a blob of the things. And let me tell you, I don't think you'll find a Distraction Carnifex as effective as three Talos less than 6" from your enemy's deployment zone turn 1.
