DNA Tracker is nuts, there's no two ways about it, easily challenging Tollbooth as the most taxing ICE in the game. When I saw that card I thought about how mighty this would be in Tennin Institute: The Secrets Within since Jinteki has been lacking taxing ICE.
This an old school Tennin Institute deck: Turtle up with ice without building a remote server then blast out those agendas with fast advance cards.
This deck is fun to play and difficult to play against, give it a spin!
