What made it perform so well against Jinteki? Was it just Deus X recursion?
Deus X is part for sure. Also, a few other things help. Mimic hnadles a large chunk of recent Jinteki ice. Since there are the 54 cards I usually found myself having cards I didnt need so I could just eat some net damage and make cheap runs. Most Jinteki decks do not play fast so as long as I was patient they could not build anything that couod stop or hurt me.
