In my experience Holo lvl 1 is more valuable when it's not even apparent that it's on the table. If you are showing your opponent 4 of the same ava 1 model then you're just saying 3 of these thing are really a schemer. Much more useful to project them as something else that they need to be worried about.
Or you could do as I did last game. I had a chaksa triad. One of them was prone in a roof. I had the same triad on the other corner. T1 one of the prone chaksas stand up and it was the Msv2 sniper. Then my opponent thought the other chaksa was also a Msv2 sniper and he was very careful. It was just a tagmaa lieutenant.
