Seer of Stolen Sight
The trigger is doing quiet double duty, and the exact wording is the whole point: it fires when artifacts and/or creatures you control are put into a graveyard from the battlefield, which means it rewards a specific kind of attrition rather than a general "things are dying" board. A sacrifice shell feeds it one permanent at a time, each death filtering or filling the yard depending on what you want. Two clauses of that text do most of the work. First, the zone matters: this cares about the graveyard specifically, so bounce and exile leave it cold, and the reward comes from trading permanents downward into your own yard rather than shuffling them to hand or exile. Second, "one or more" cuts against how it reads: a board wipe that clears half your creatures at once resolves as a single surveil, not a stack of them. So the payoff lives in staggered, repeated deaths (sacrifice loops, token trades, aristocrat chains) rather than one big simultaneous exchange. Surveil is the correct verb over a raw draw here, because a Warlock built to loop the yard cares more about which cards land in it than about pure card count. Menace on the 2/3 keeps the body honest while the engine ticks: it can pressure life totals early and still connect once the ground stalls, so the aristocrat plan and the beatdown plan share a slot instead of competing for one.
