Slot this into Gagarin, rez it and let it stew while the runner is too busy dealing everything else you got.
Then watch their face when they get killed by a Woodcutter!
Or, more realistically, you just make an Ice Wall hilariously high strength or a Mausolus instantly impossible to run through.
That, or they just fork over the 5 to trash it (or 2, if they can do magic). Either way, not a bad card.
