Mycoweb looks sweet.

Synergies:

• Can do 2–3 net damage (for just $0–$2): if you resolve a Bathynomus (sentry with three-damage sub, thanks @Cobalt), or a Karunā (sentry with two-damage sub), or an unrezzed/archived Anemone (for 1[$] total, by installing it in front of Mycoweb, since Anemone reads When you rez this ice during a run against this server, …).

• Can do 5 net damage(!): three from a cheap Sentry, like Bathynomus (3[$]-to-rez); plus two from a (pricy) Code-Gate, like Vampyronassa (7[$]-to-rez).

• Can “mimic” an EtR: with Flyswatter (or any “new Lotus Field”?).

• Could even “mimic” a Destroyer: with out-of-faction ICE.

Related:

• Like Ivik (a Barrier that's cheapened by Code-Gates), it cares about icetypes.

• Like Vampyronassa, it's a four-sub Code-Gate. Its ceiling is higher: install and rez some trashed ice in the third-outermost position (for two credits less, rather than two credits more), then end the run as well as dealing damage. But its floor (given ice-empty Archives and uninstalled non-Barriers) is much lower: literally ↳ ∅. ↳ ∅. ↳ ∅. ↳ ∅.

Direct Subroutine Resolution:

• Unlike most other Resolve 1 subroutine on a rezzed …. effects (like Ravana 1.0), Mycoweb can resolve subroutines on unrezzed ice (if you can afford the discounted rez-cost) and even trashed ice. CF. The banned Nanisivik Grid, which could also resolve unrezzed/trashed subs; but ignoring rez-cost, barrier subs too, and unbreakably (being an upgrade). This makes it less “conditional”, while still giving you the implicit strength-boosting (Mycoweb has 5 strength, Bathynomus/Anemone have less); as well as flexibility (like a ↳ Do 2 net damage or end the run.), FWIW.

• While splitting a Do N damage. effect across N multiple smaller ↳ Do 1 damage. subroutines is better in general (being more taxing to fully-break), keeping it on a single larger subroutine is better with resolution effects. Same with other numerical effects besides damage-dealing damage (like credit-zapping).
