Returned Centaur

The 2/4 body is the tell: this is a blocker whose combat stats are almost beside the point, a wall that parks in front of aggression while its enters-the-battlefield trigger does the real work. That work faces two directions, and the reason is a single word in the trigger. It reads "target player," not "target opponent," so the four cards can hit either graveyard depending on what the deck wants. Aimed across the table, it is incidental library disruption that rarely matters on its own. Aimed at yourself, it dumps four cards into your own bin in a single turn, fuel for the recursion and reanimation plans black has always been built to feed. That flexibility is what makes a body like this the connective tissue of graveyard strategies: a wall and an engine folded into one card, so the same four-drop slot services a control plan thinning the opponent and a self-mill plan stocking its own yard. The rate is not pushed and the body will never threaten anything, but that is the trade. What you are buying is the four cards that land the moment it resolves, and a patient blocker to hold the ground while the graveyard fills.
