The Gitrog, Ravenous Ride
The frog that eats lands is a long-running character, and every incarnation has been built around the same tension: black-green wants graveyard value and land drops in the same package, but the color pair has always paid for that engine with a downside stapled to it. This version resolves the tension differently by routing the drawback through the Mount mechanic. Saddle 1 asks you to tap a creature to prep the ride; the payoff clause then asks you to sacrifice one of those saddlers on connection, so the entire loop is priced by the power of whatever you fed it. A humble one-drop saddler nets a card or two and a land or two from your hand; commit a larger body and the reload scales with its power, which is where the design gets sharp: the fuel you spend never swings itself, so the Gitrog converts a stationary creature's power directly into a refill of cards and lands entering tapped for next turn. Haste and trample are the delivery system, helping the 6/5 attack the turn it arrives and pushing damage through chumps so the sacrifice payoff fires as an immediate threat rather than a distant promise. Everything hangs on landing combat damage, and that red-zone requirement disciplines the whole card-and-land avalanche: no swing, no draw, no ramp. It wants a board where your small creatures exist to be eaten and the Mount exists to carry them into the kill.
