This is a fairly decent card I've been seeing in a variety of anarch decks, and even outside anarch a bit. Crew is ice trashing when strength hits 0, similar to Chisel. However, crucially, Crew fires during the encounter, while chisel only works at the start. This means that Crew works with Leech, allowing you to lower ice strength to zero with you Leech counters then trash it with this resource. This affords you a good deal of flexibility. Leech is a card that has uses outside of ice trashing, helping to enable the fixed strength or expensive to raise anarch breakers like Buzzsaw, Cleaver, and Mimic. Devil Charm was usually comboed with Chisel, but it wasn't used much outside of the combo. Of course, nothing says you can't run both together, but Crew being one less influence makes it more splashable, and I've seen it in some AI decks to deal with problem ICE.
The tag ability is also useful, but mainly to combo with itself. Crew can very easily trash cheap gear checks from 0-2 strength, letting you run early while maintaining a threat on servers. Late game though, Crew can still serve to remove problem ice, but it starts to need its combo pieces, rather than working on its own.
