Ivory Tower 2.5 (Final Edition)

-1 Dino, +1 Djinn

I really think you want Djinn in there to help with memory and tutoring. That way can get your Datasuckers and Medium/Nerve Agent when you need them. Plus it can host an SMC while you are rig building or a Sneakdoor/Keyhole afterwards.

Test Run, Clone Chip and SMC seems like tutoring enough for me. Great deck, while a little hard to play with it.

This looks pretty good for a Professor deck! I agree with adding a Djinn for the virus programs plus hosting. Also, I might think about throwing in a Sharpshooter and a Torch. Being able to blow past an Archer for 2 credits is nothing to sneeze at, and you already have the Test Run/Scavenge combo ready, so getting a Torch out should be easy. So: +1 Djinn, +1 Torch and +1 Sharpshooter.

Test Run, Clone Chip and SMC seems like tutoring enough for me.

Test Run is for Femme and to use with Scavenge to get out the big guns. Clone Chip is for Faerie or to bring back a SMC or a trashed breaker. Personally I don't really want to be wasting an SMC on a Datasucker. If I use it for Djinn I have every virus in my deck available without using one.

It's also +2 MU in a deck that desperately needs it.

With Dino and Akamatsu, I don't see why more MU. Djinn would be good for 3 cards, but removing a Dino is not a good idea. Now this deck seems to survive without plascrete. Maybe removing for a Djinn....I'm not so sure thought...

I understand wanting to keep 3 Dino to make sure you can get your hands on it. Maybe you can cut a Mem chip for the Djinn? They both serve the purpose of extra memory, you gain some utility and it only costs 1 more credit.

I still wouldn't use Djinn. He only serve as extra memory if he is installed first. This means that most of the time you will have to tutor it with SMC or with Test Run + Scavenge. This deck, while a little hard to pilot, seems ideal to me. The only thing that I would add here is an Imp.
