We are working on different ads styles all the time to make sure they convert, I've see the Deck ones before and whilst they look good, I believe they are paid on a CPM basis so are more for branding than actual clicks (but that doesn't mean we won't try an adstyle that looks like that).

We've built our system to be quite flexible, we can make changes and push it across the whole network or just a small part within minutes for a nice a/b test
