I haven't got the link (the isotropic links never seem to work properly for me anyway), but if I hadn't been reading about these things here I may not have spotted the double-Tac deck in the game I played today - Baron and Treasury for extra $, as well as a Haggler my opponent Masq'ed to me, Masq for some light trashing, Warehouse for cycling, and Mining Village to help me play a few extra terminals. I think I managed to play Tac in all but one turn once the engine got started, and bought a Province plus another engine piece in most of those turns. Possibly my favourite part of the game, though, was when we'd split the Treasuries evenly, I'd top-decked all of mine, letting my opponent grab one with a Masq, only for me to take it back in exactly the same way a few turns later.
