If you have no influence for DZMZ Optimizer and you need additional after installing whatever console you choose to install, then T400 Memory Diamond is there to help you out. On top of that, you get to have more card in hand. Maybe saving you from double Neurospike or double Punitive Counterstrike.
Of course, paying 2 is not cheap, so you better make those worth it. Unless you are going for a deck that need a big hand size.
The additionnal hand size is not to be understated. Just like for the corp, it allow you have more options in hand to counter the corp. It also let you draw a lot of cards before needing to discard a card.
The art is nice and easy to see on the table. The quote is flavorful. The card feels good.
