Decoders. If you want some good decoder, you go to the Shapers, so no suprise that these precious little thing is burning green.
Ok, at 9 you can say anything about the Torch, but not "little thing". But if you are not running with stealth credits and Refractor or Yog.0 and Datasucker this is the most efficient universal decoder you can get.
Cyber-Cypher has the same strenght, but can be used only on one server.
At this moment, the dawn of Order and Chaos, 10 out of 33 codegates have strenght higher than 4. Torch burns thru such fan favourites like Chum, Lotus Field (something that Yog.0 can break only when installed on Dinosaurus ) or Viper for one or two creds. Tollbooth is five .
So if you are not planning on bringing D4v1d with you, this is good starting point for stronger codegates that are coming with Order and Chaos: Checkpoint, Wormhole and Orion. Criminal Leviathan can be more expensive at the middle-range ICE.
But 9 is serious money. At the cost of 4 influence, you don't really have much options but to play it only in the Shaper deck, which heave the most tools to help you out bring it fast and cheap. You could always use Self-modifying Code, but do you really want to pay 11 ?
More useful is Test Run + Scavenge combo, which lets you install it for 3 credits. If you are playing Prepaid VoicePAD, it can be even cheaper. Kate "Mac" McCaffrey: Digital Tinker can install it for 5 with Modded. And if you manage to put it in your heap, you can use Anarch Retrieval Run.
There could be also some cases when using Code Siphon has some point. But Test Run Scavenge is most reliable in-faction.
It's fat, it's expensive, but I love my little Torch. You need to build economy around this card, but when it works, it's fun and efficient.
