Golgari Longlegs
Five power for five mana, with hybrid pips that are the entire reason this card exists. The double cost means either half of a black-green mana base pays for it without strain: a mostly-black deck splashing the faintest green, or a green deck running a single Swamp, can field this insect without contorting its lands. That is the structural job a common-rarity hybrid creature is built to do: smooth out a two-color archetype's curve at the top end without demanding a clean mana base to support it. There is no triggered ability, no evasion, no recursion to read past the stats, and that plainness is the point of where it sits. It was made as a workhorse for an attrition-minded, graveyard-leaning guild whose midrange fights are meant to be settled by creatures that outsize the board: big enough to trade up or punch through, cheap enough on color commitment to never rot in hand for want of the right land. The 5/4 body is the kind that closes games without inviting the premium removal a true bomb would draw, which is exactly the profile a curve-topper wants when it is meant to be unremarkable and reliable rather than feared. Honest filler for the guild it serves, and quietly outclassed wherever the power bar has since climbed past a vanilla beater.
