Call of the Herd

Two creatures from one card, paid for in two installments. That was the proposition flashback brought to the green beater, and Call of the Herd is the clean demonstration of it: cast it once for a 3/3 Elephant, let it die or trade, then spend a little more from the graveyard for a second. The math that makes this work is card advantage smuggled into a body. Most three-mana creatures are one card; this is functionally two, with the second deferred until you have the mana and the need. The cost split is the discipline that keeps the rate from being broken: the flashback half is pricier than the front half, so the second Elephant comes online a turn or two later than the first, and the graveyard cast exiles the card for good. What it answers is the perennial weakness of midrange ground attackers, which is that they get traded down and run out of gas. A creature that refuses to leave the game until you have collected both halves does not run out as fast. That unglamorous resilience wins long games of attrition by simply having more bodies than the opponent has answers, and it set a template green has returned to whenever it wants a beater that doubles as insurance against removal.
