Green mana dorks usually pay a tax: the 1/1 body becomes a liability the moment the ramp curve stops mattering. TMT softens that tax in two ways at once, and Frog Butler is the card that converts the softening into a real pick.
The format is medium-speed with one-to-two playable removal commons per color, which means the 1/1 lives long enough for the deathtouch to actually matter on defense. More importantly, this is a legendary-matters environment where the splashable hybrid uncommons and the two-color legends at uncommon reward decks that can cast off-color spells on curve. A turn-two fixer that produces any color is doing work GU Ramp and BG Food specifically need, and it is doing it on a body that trades with a Foot Ninja in the air-attack lane once you spend the reach activation.
P1P4 to P1P6 in any green deck with an uncommon legend pulling a splash, higher in BG Food where the deathtouch trades up into the format's bigger ground threats and the body itself feeds a sacrifice outlet. Maindeck everywhere green, never sideboard. The punisher is Grounded for Life: a tapped 1/1 is exactly the target that spell is priced to kill, so the tap-to-ramp line is genuinely risky against white decks holding two open mana. Stomped by the Foot kills it for free.
The reach mode is the clause that ages well. By turn six the format's Flying threats (the air-based legendary Turtles, the Sneak fliers) need a real answer, and a activation on a card already in play is the cheapest interaction green has against them.
