I'm surprised Security Subcontract card doesn't see much play. Now yes, the cost of a piece of ICE is 2 clicks and its rez cost, which is a "bad trade" if you spend yet another click using Security Subcontract for 4 credits. But in late stages of the game, when you no longer need to guard your drip assets, you can decommission small taxing ICE for an unexpected burst of credits. If for instance you've been siphoned to 0, have a Beale/Psychographics in hand & a Security Subcontract in a remote, and you're sitting at 5 points, you would gladly trash any piece of ICE for the win.
Theoretically Ob Superheavy Logistics gives this card a reason to exist as you can use it to trash one piece of ice on an empty server and then use it to install and rez another piece of ice somewhere else... Except Svyatogor Excavator is RIGHT THERE and is better in every way BUT the money you get from it. The only advantage would be to have both at the same time to make sure you have ways of trashing cards.

The issue is that this use case is very narrow. It's a dead card if you draw it early, and you need to use it twice for it to be better than Beanstalk Royalties, which is generally considered a pretty weak economy card. It's best use is probably in decks that only pack ice as gear checks, and aren't trying to tax them once they find their breakers, but those decks are usually trying to go very fast, while this card is painfully slow.
