Roaring Earth

Most landfall payoffs pay you once per trigger and stop there; the counter here is the point, but it isn't the whole design. What makes this a two-card investment in one slot is the channel clause, which hands the enchantment an exit ramp when the board is stalled or the game is already lost. Flood out and the counters have nowhere useful to go, so instead of a dead card you discard it to turn a land into a hasty threat that keeps its land type: an attacker that still taps for mana, sized on the spot by however much you can pour into X. That dual identity resolves the classic problem with build-around enchantments, which is that they beg for a critical mass of lands entering and then rot in your hand once you flood past the point of usefulness. The landfall side rewards the fetch-heavy, extra-land decks that want to grow one creature into a finisher across a turn cycle; the channel side is insurance against exactly the draws those decks produce. Note the target restriction on both halves: the counters land on creatures, Vehicles, or lands you control, never across the table, so it is purely an engine piece, not interaction. The design is a single card asking to be two different tools depending on which resource you're short of, and discarding it is the friction you accept to get both.
