Antiquarian Oracle

Flying, vigilance, scrylink (Damage dealt by this
creature also causes its controller to scry that many
cards.)
Artifact cards with mana value 4 or less in your
library have scrycast {1}{w/u}. (If you see an artifact
card with mana value 4 or less while scrying, you
may reveal it and cast it by paying {1}{w/u}.)
