The rate is the whole negotiation here: a 2/1 body that fuels itself only when it swings, which means the card draw is bolted to the riskiest thing this creature can do. A 2/1 dies to almost everything, so the ability rewards you precisely when you are willing to send a fragile attacker into an open board and let it trade or connect. That constraint is what keeps a repeatable draw engine off a body this cheap: you do not get the card for casting it or tapping it, you get it for putting it in harm's way, and the life loss compounds the pressure in a color that already treats life as a resource to spend. Aggressive black decks have long wanted attackers that refill the hand as they empty it, from Dark Confidant's upkeep gamble to the raft of raid and menace draw-on-combat creatures that followed; this sits in that lineage but pins the payoff to the attack step specifically, so it is at its best when the board is tilting your way and worst when it is stuck staring down a blocker. The Elf Warlock line is doing quiet tribal work, but the design is the more interesting part: an aristocrat-adjacent draw creature whose upside and its downside share a single trigger.
