Scry Cards to Date (Before Theros)

There have been 22, in three sets, and only one has been reprinted across these. All have been printed at common and uncommon, and there have been one of each for lands, enchantments and artifacts. Then we also have 8 instants, 5 sorceries, and 6 creatures.

All red and white have gotten so far is two instants each. Green has one creature and two instants. Black has two creatures, an instant, and a sorcery. Blue has gotten, understandably, 9 of the 22 cards: 3 creatures, one enchantment, one instant, and 4 sorceries. 

Here is the rules text. Scry 2 has been most common, and there have been no Scry X cards to date.
