Mutant Town

Functionally Thornwood Falls: the GU entry in this set's gain-a-life tapland cycle, and the reskin is the whole story here. The fixer underneath is the one green-blue decks have run for years, doing nothing the original didn't, and the only genuinely new thing is the costume.

Which leaves the Limited read short, because TMT doesn't bend a plain tapland much. Fixing is already good in this format, and the set leans on hybrid commons (Mechanized Ninja Cavalry, Putrid Pals) plus utility lands at common to keep two-color decks honest, so a vanilla GU dual is competing for slots rather than filling a gap. The legendary-creature theme does reward staying on two colors with a splash, which is the manabase shape this land suits. Take it when your GU base is settled and you want one more clean source; pass it for any actual playable. Speed is medium and the tapped clause is a survivable cost, not a deal-breaker, but it is still a tempo point a deck on curve would rather not pay. The lifegain is a rounding error against the Sneak attackers, not a payoff to chase.

Functionally Thornwood Falls. In Commander the tapland slot is the easiest part of a green-blue manabase to fill and the easiest to cut: it enters tapped, which a hundred-card deck notices more than a Limited pool does, and the single point of life is a rounding error rather than a payoff. It maindecks in budget Simic builds where the alternative is a basic with no upside, and it gets shaved the moment the deck can afford untapped duals or fetchable lands. The reprint adds a copy to the pool and nothing to the read.

Functionally Thornwood Falls, which in Modern means it does nothing. The format's green-blue manabases run on fetches, shocks, and a deep bench of untapped duals; a tapland that gains a single life and only fixes two colors has no seat at that table, and the original never had one either. This printing adds a copy to the pool and changes the read not at all. Legal, and so far untouched by tracked tournament play, which is exactly where the original sat.

Functionally Thornwood Falls, and Standard does nothing to move that read. It is a Simic tapland whose lifegain trigger is a rounding error rather than a payoff, and green-blue is exactly the pair least set up to make the gain matter. In a format with real shocklands, surveil lands, and the various untapped duals that have shaped recent Standard manabases, an enters-tapped gainland is the floor of the fixing options, not a slot you reach for. It is legal but has yet to register in tracked tournament play, which is the expected outcome: the GU decks that could run it have better lands available and no reason to eat the tempo hit.

If you are building a budget Simic base with no other fixing, it does the job a tapland does. That is the whole story.

Functionally Thornwood Falls, which tells you everything Pioneer needs to know: the format has Simic taplands with upside in every direction, and a plain gain-one-and-tap dual is the bottom of that stack. Pioneer green-blue bases reach for untapped fixing, scry lands, or pathways before they reach for a tapland whose only rider is a life point green-blue cannot meaningfully bank. It is legal and has yet to register in tracked Pioneer play, which is the correct outcome for a strictly-worse option in a deep card pool. Nothing about this printing moves it: the decks that wanted the original never wanted it here, and adding a copy to the pool changes neither.

Functionally Thornwood Falls, the green-blue entry in the gain-a-life tapland cycle. Pauper has a deep bench of these duals, and nothing about this printing changes the calculus: Simic decks in the format already want fixing that comes in tapped only when they can afford it, and they reach for it sparingly, a one-of at most when the manabase needs the extra source. The lifegain is the same rounding error it has always been, not a payoff. It adds a copy to a pool that was never short on copies, and the decks that pass on the original pass on this for the same reason: the tempo loss is real and the trigger does not buy it back.

Functionally Thornwood Falls, which tells you everything Vintage needs to know: it is a tapped green-blue dual whose lifegain rounds off the tempo it costs, and in a format defined by Moxen and one-mana interaction, a land that enters tapped is a non-starter. Nothing in the format wants this. It is legal and has yet to register in tracked tournament play, which is the correct outcome for a budget fixer in a pool that runs original duals and fetches. The reprint adds a copy to the pool and a Simic-flavored option to kitchen tables, and nothing else.

Functionally Thornwood Falls, which tells you the entire competitive story before it starts: a tapland in the gain-a-life cycle has never had a home in a format defined by Brainstorm, fetchlands, and dual lands that produce two colors untapped on turn one. Legacy manabases do not pay a tempo turn for fixing this slow when the originals of every dual it would replace are legal and cheaper on the play. It is legal and has yet to register in tracked tournament play, which is the expected and stable result, not a gap waiting to close.

So the reprint changes nothing about the card's place here, because the card had no place here to begin with. It adds a copy to a pool that did not want the copies it already had.
