Yagura is the best ICE ever for turn 1 RnD. Especially good in an “only Code Gate in the deck” kind of situation - you’re paying 1-2 credits to gear-check decoders, because running through Yaguras naked, while tempting at first, is not a sustainable long-term plan.
Swordsman is pretty meh, I’d only run 1 of them, and probably only if I’m also running Chum (because that actually makes it somewhat taxing and out of Mimic range).
