If there's no ice protecting a server can I run on it and jack out without accessing to have it count as an unsuccessful run to intentionally get a tag / trigger unsucessful run effects?
jacking out to have unsuccessful run on purpose? (Masanori)
Yes.
Are you thinking of doing something like:
Click 1) Failed Run, take Tag
Click 2) Data Leak Reversal to trash corp card
Click 3) Data Leak Reverasl to trash corp card
Click 4) Shake Tag or Data Leak Reversal to trash corp card (if you have Joshua B.)
w/ Joshua B.
Click 5) Shake Tag +New Angeles to avoid Joshua B. tag
yea something like that. Can new angeles city hall be used on the corp's turn to shed the tag you'd get from joshua?
Yes. New Angels is a conditional ability. See page 21 in the rulebook.
New Angeles is a prevention effect, which means you use it as you're getting the tag, not later.
