I've been running Davinci in a Armand "Geist" Walker: Tech Lord deck and it is perfect in there!

Since you can only install cards less than the power counter's on it, you need low cost install cards, like the Forger, Clone Chip, Faerie, Shiv, Spike, and Crowbar. The instant speed install from the grip lets you run super aggressive early on, and a single counter on it gives a tonne of options plus the icing on the cake card draw. It's super fun to let someone play SEA Source and then bring out a Forger to clear it and get two draws out of it.

Once I needed a faerie but didn't have it. I used it to install a clone chip, draw a card but not the faerie, use the clone chip to re-install davinci and finally draw the faerie, and then use the davinci again to install faerie drawing a 3rd card and not being killed by a sentry
