Burner: Single handedly forcing Corps to ice up HQ first against Shapers

Functionally Burner is similar to but much less random than Embezzle trading the ability to have an insane upside that Embezzle has with, umm, being a fantastic card. There really isn't much downside to this card beyond it being a little less damaging when your opponent has a Spin Doctor or some other instant speed ability to manipulate RnD (and even then you playing Burner forces the use of these cards).

The important three points when playing Burner is that it is always guaranteed to do some damage, it does so in a way that dodges traps or Oppo Research and that said damage is controlled. If you were to legwork into HQ and see 3 Ice or Operations, that would obviously be a wiff. Even with tools like Imp added in you might trash the "objectively incorrect" card because you are seeing the cards one at a time and might waste the imp on the wrong card. And if you legworked into 2 Snare! and a Fujii Asset Retrieval you are probably heading home in a body bag.

Burner gets around both these issues by showing you all 3 of your choices at the same time and giving you full control of where they go, top or bottom, which can be different (top the Agenda, bottom the Oppo Research ). It also does this without needing to combo with any other cards, hence a Shaper Aniccam event heavy deck running this card would have excellent HQ pressure that must be respected, even with no other HQ cards. And even with just a Twinning, Burner plus Twinning on a standard 5 card hand Corp will let you see and steal everything, which is great fun all around.

All up a fantastic Shaper card. At 3 inf it is a bit difficult to import but it is still possible for other factions. And if you as the Corp leave HQ open on the Runner's first click you have to be aware that you might be signing up to get all your fun tools chucked to the bottom of the deck.
