Enhanced Surveillance

Surveil's design tension is that it asks two things of a deck at once: it filters draws and it seeds the graveyard, and a shell built to exploit one usually wants more of the other. This enchantment scales both jobs together. Looking at two extra cards each surveil turns a thin sliver of selection into a genuine dig, smoothing land floods and finding the spell you need several turns sooner, all while feeding more of your library into the yard for whatever payoff wants it there. The second ability is the tell about who this was built for. Decks that pour their library into the graveyard, whether to enable flashback, escape, delve, or a deck-out kill, eventually hit the wall every self-mill strategy fears: the empty library that loses on the draw step. Exiling the enchantment to shuffle the yard back in is an emergency reset, a one-shot insurance policy against milling yourself out. That pairing is the interesting part. Most graveyard payoffs sink your library with no way back; this one lets you mill aggressively, deepen the selection through surveil, and still hold a button to undo the risk before it becomes lethal. The cost is that pressing the button ends the surveil bonus, so the enchantment sits in quiet friction with itself: the more you lean on the digging, the more reluctant you are to spend the safety valve. It is a build-around that means little outside a self-mill shell, though even a deck that never surveils can still spend it as a single graveyard shuffle in a pinch.
