Oculus takes from your library; it just triggers on your opponent’s turn.
I also found myself cutting a few unnecessary tempo payoffs recently. The deck is often fine playing more generic threats; the critical density of cheap spells/interaction is usually the harder part to draft in most cubes I’ve tried. You could definitely shave iconoclast if necessary. Delve or pseudo-delve cards like the aforementioned Oculus can also serve as spell velocity payoffs that can be played in other decks more easily.
