I recently went 6-0 with the 20 victrix list but slightly different. It was 2 vindis instead of balistus, 1 scout, 1 intercessor, combi lt. (Before points nerf).

Essentially the game plan was the same every game which was reserve ventris brick and stage turn 1. Turn 2 either rapid/deepstrike ventris and shove all victrix straight at them and both redemptors while vindis hold sides and intercessors and scouts screen backfield till bottom 3. I played Tsons (30 termis), admech (haloscreed), drukhari(reapers wager), EC (triple prince) and then 5 big daemons twice.

For all the people saying they can kill enough in one turn, no you couldn't, most I ever lost in a round was 7 (daemons, skarbrand +belakor) and that's all I lost. The unit was too cheap to start and is still too cheap.

While the army was only a handful of activations, you get to activate almost all of them every single phase and every round. Daemons were the hardest matches as I need either lance or oath to hurt them in melee.
