EDIT: 2×Spree won Worlds! It moved around Botulus and Physarum Entangler to break/bypass, Ika to save credits, and Pichação to gain an extra click (see “Netrunner is a game we play with our bodies [Worlds2024 1st]”)
IIUC, by moving around a Chisel before each approach, Spree can accrue up to 3 virus counters
on it off a single run, while also shrinking all three ice on a server by an average of at least −2 strength
each (cf. a local K2CP Turbine), even post-purge. Or, off just one of Spree’s three ‘charges’, you can move a big Chisel onto an brutal piece of ice (like an Anansi or Trebuchet) that's outermost, after having built up several counters on it by running through or bumping off a gentle piece of ice (like an Ablative Barrier or Ping) that's elsewhere, which UAV can't do (even if it could yank back viruses, it would reset their counters anyways).
P.S. Design-wise, my favorite Shaper effects are the “moving stuff around”:
- re-
hosting
trojans between ice (Spree, Urban Art Vernissage);
swapping
ice between servers (Tāo Salonga, Escher, Inversificator, Cordyceps);
- re-
arranging
cards within a deck (Indexing, Cataloguer);
- “spinning” (
uninstalling
+installing
) programs between zones (Simulchip, Scavenge, World Tree);
- “painting” between
ice subtypes
(Pelangi, Panchatantra, Paintbrush);
- and
moving
power, virus, or even advancement counters between installations (cf. a “Trick of Light × Exploratory Romp”)…which haven't been printed yet.
So I hope Spree will still see some play in Arissana, despite how good Burner and Trick Shot will be in any Shaper.
An astute observation regarding Chisel. Not sure I follow your logic in saying least -2 strength to each ICE. Assuming a server 3 ICE deep which are not destroyed as a result of hosting Chisel and no virus counters to start, we should see -1, -2, then -3 strength I believe. Of course, interactions with Monkeywrench, which can also be moved, open up a whole range of new possibilities.
