The Missing Ingredient v2 (puzzle)

This deck's done pretty well for me up to now. I feel like everything else is there but there's one thing missing. I'm hoping you might help me find it.

The influence use is quite odd but I like the surprises. I considered Cold Site Server for defending the remote, but Red Herrings or Reduced Service squeeze the credits so I think they're more effective. For ice, you could choose something like Cortex Lock or Zed 2.0 though I'm not sure they're much better.

I'm struggling to put my finger on it. Just feels like something you would commonly get isn't there.

Weirdly, I believe you could think likewise for this write-up!

Do you know the missing ingredient?

(if you do, just post something below to prove it; don't spoil it for others)
