Interactions with Ice form a unique and interesting aspect of Netrunner. I was thinking of design space when it comes to ice and what would create interesting interactions. I think that ice with a “When first encountered” ability could change things up. For example:
Barrier, Trap, AP
“When first encountered, do 1 net damage.”
-> End the run
This ability would only trigger the first time the runner encounters the ice, but would stick around, unlike other trap ice. These ice would have interesting interactions with derezzing, recursion, and unused cards like Midori. Here’s another example:
“When first encountered, end the run.”
Aside from these specific examples, what do people think of the mechanic in general?
