This card is incredible, and is one of the best things you can find in your opening hand other than Host Spider and/or your other Interfaces. It's conditional card draw which puts the most important cards in your deck into your hand. Importantly, even if you don't hit any Identity-specific cards, you are still thinning your deck, and getting you closer to the cards that are, like your missing interfaces and your All Systems Go!.
Early game, it's fantastic as it helps you set up quicker, getting you to those interfaces you still need and removing basic/aspect cards that aren't as helpful at that point. Late game it's fantastic as it cycles you to your All Systems Go!, VEN#m, and less importantly, Web-Trap and Rapid Deployment.
Given that you only mill two cards in SP//dr mode, and identity-specific cards make up less than half of your deck (even less so after playing this card and getting some interfaces out), you won't always get hits. But a single resource for persistent cycling and card draw throughout the entire card game is phenomenal. Don't overlook this card.
