Collectors have not even reached Delta Reign prerelease weekend yet and the name of the set after it is already doing the rounds. PokeBeach says it can reveal that the next main English set will be called Flowing Fists and will star Mega Lucario Z ex. That claim is why this story sits in Rumor Mill. The set name and the February dates come from reporting rather than an official announcement and we are treating them that way until Pokémon says the same thing in public.
The reported timeline
Under the PokeBeach report the set would launch on Friday, February 5, 2027 and prerelease events would run from January 23 through January 31. Other outlets have since repeated the name and the dates while crediting PokeBeach as the first report. The English set would be based on Aura Seeker in Japan and that Japanese set is reported for November 27 with the same lead card. If that Japanese date holds the first full look at most of Flowing Fists will come from Japan more than two months before English packs arrive.
The card at the center is already real
Mega Lucario Z ex itself is not a rumor. Pokémon showed the card during the Worlds closing ceremony in August and the English card art is already public. It is a Stage 1 Metal card that evolves from Riolu and carries 330 HP. Its Ability is called Aura Seeker and it can be used once during your turn while the card is in the Active Spot to search your deck for a Supporter card and put that card into your hand. Its attack Dancing Fist costs two Metal Energy and does 120 damage plus 120 more damage when the opposing Active card is a Pokémon ex. That is 240 damage into the cards this era is built around for a two Energy attack.
The risk matches the power. When a Mega Evolution Pokémon ex is Knocked Out the opponent takes three Prize cards and this Lucario is weak to Fire and resists Grass. Its printed number is 058 out of 080 and its set code reads FLO with illustrator credit to takuyoa. Those printed details are visible on the card itself and they are the strongest clue in the whole story because the numbering already tells collectors the size of the main set they would be chasing.
A built in answer is already in the set
Sigilyph ex gives the set an early talking point beyond its cover star. Portal TCG lists Sigilyph ex as a Psychic Basic card with 210 HP and the Ability Mega Protection. That Ability prevents all damage done to Sigilyph ex by attacks from opposing Mega Evolution Pokémon ex. Wargamer makes the same point about the Ability and reads Sigilyph ex as a wall that could help keep Mega decks in check. In plain terms Lucario cannot damage Sigilyph with its attack at all while Sigilyph can still hit back with Power Cyclone for 140 damage.
Why the size and the name both matter
A main set numbered to 080 would continue the recent English pattern of smaller sets built closely from one Japanese set. PokeBeach puts Perfect Order and Chaos Rising and Pitch Black in that same line and Portal TCG gives the same rough main set size for those releases. For master set collectors a smaller main set can sound like relief after the scale of the anniversary year. Our conjecture is that the chase will still live in the secret rares and in whatever special illustration treatment Lucario receives so a short main list should not be read as a cheap set to finish. That part is conjecture and not a reported fact.
The name carries its own nostalgia play. PokeBeach and Portal TCG and PokePursuit all note that Flowing Fists points back to XY Furious Fists from 2014 and that set was headlined by M Lucario EX. The new lead is a Metal card rather than a Fighting card and PokePursuit notes that Metal matches the Steel side of Lucario in the games. More than a decade on the callback gives older collectors a familiar hook while the Z form gives the set a card no binder has carried before.
What to watch next
Watch Japan first. PokeBeach expects Aura Seeker to be officially revealed within the next week or so and a full Japanese reveal would confirm or correct most of what English collectors are now planning around. Watch for an official English announcement as well because only that announcement can move the name and the February dates out of Rumor Mill. Until then the smart collector move is patience. Let Delta Reign have its November moment and use the Japanese spoilers as your planning list rather than paying early prices built on a reported name alone.
