Stonefare Crocodile

Lifelink hidden behind a black mana symbol is the design tell here: this is a single-color frame stamped with a two-color identity, a green beater whose drain trick only fires when there is black mana to feed it. The 3/2 body is an honest green common rate at , but the lifelink costs every turn it wants the keyword, so the gain is never free. Three mana per swing, on top of committing the creature to combat, turns the lifelink into a recurring tax rather than a passive upside; it pays only in a deck running both colors with mana to burn and a swing worth converting into life. The split-cost activation is a familiar trick for welding a guild identity onto a mono-colored card, letting a green creature still read as belonging to both halves of its pair at the table. The result is modest by design: the activation cost caps how fast the lifegain can snowball, and the slim toughness keeps the croc vulnerable in the very combat it wants to attack into. What it offers is incremental, a few points of life accruing one attack at a time across a long, mana-flush game, never a runaway.
