Blacephalon-GX, Heat Factory Prism Star, and More from SM8 Revealed!

The Japanese Pokemon Card website has officially revealed SM8 Explosive Impact!

As posted three months ago, it’s Japan’s Johto set, will release on September 7th, has 95 cards, and will feature Lugia-GX and Blacephalon-GX. It will be released in America as Lost Thunder on November 2nd.

Update (literally right after posting): Blacephalon-GX, Naganadel, and Heat Factory Prism Star were just revealed! Thanks goes to Bangiras and Jake C. for the translations!

Blacephalon-GX – Fire – HP180
Basic Pokemon (Ultra Beast)

[R] Bursting Burner: Your opponent’s Active Pokemon is now Burned and Confused.

[R][R] Mind Blown: 50x damage. You may send any number of [R] Energy attached to your Pokemon in play to the Lost Zone. This attack does 50 damage times the number of cards sent in this way.

[R] Burst GX: Discard 1 of your Prize cards. If that card is an Energy, attach it to 1 of your Pokemon. (You can’t use more than 1 GX attack in a game.)

When your Pokemon-GX is Knocked Out, your opponent takes 2 Prize cards.

Weakness: Water (x2)
Resistance: none
Retreat: 2

Lugia-GX – Colorless – HP190
Basic Pokemon

[C][C][C] Psychic: 30+ damage. This attack does 30 more damage times the amount of Energy attached to your opponent’s Active Pokemon.

[C][C][C][C] Wadatsumi’s Spear: 170 damage. This Pokemon can’t use Wadatsumi’s Spear during your next turn.

Once during your turn (before your attack), you may attach a basic Energy from your discard pile to this Pokemon.

[C][C][C] Turning Point: 80+ damage. If you have exactly 3 Prize cards remaining, this attack does 80 more damage.

Weakness: Psychic (x2)
Resistance: none
Retreat: 1

Heat Factory Prism Star – Trainer

You can’t have more than 1 Prism Star card with the same name in your deck. If a Prism Star card would go to the discard pile, put it in the Lost Zone instead.

Once during your turn (before your attack), you may discard a [R] Energy from hand. If you do, draw 3 cards.

As long as this Stadium is in play, whenever a player uses an Item or Supporter card from their hand, prevent all effects of those cards done to this Stadium.

This card stays in play when you play it. Discard this card if another Stadium card comes into play. If another card with the same name is in play, you can’t play this card.

The Japanese booster box reveals that Milktank, the Scizor line, and the Ampharos line will be part of the set. On a related note, Ampharos-GX will be included in SM8 Dark Order.


Card sleeves featuring Lugia, Suicune, Blacephalon, and Lusamine will be released alongside the set, as will a deck box and playmat featuring Lugia. The Lugia deck box and sleeves will be sold in stores everywhere, the Lusamine sleeves and Lugia playmat will only be sold at Pokemon Gym tournaments, and the rest of the sleeves will only be sold at Pokemon Center stores.

It’s pretty likely Suicune-GX will be in the set after its exclusion from the Legends of Johto-GX Box. They were probably saving it for this set.

An “Explosive Impact Pokemon Center Limited Set” will be released at Pokemon Centers the same day as the set for about $90. It will include two booster boxes of the set. More notably, it’ll include a deck box and set of card sleeves featuring Whitney and her Miltank.

It’s possible Whitney could be a full art Supporter in SM8 judging by her product appearance here.

Also revealed were the product images for the previously-announced “Alola All-Stars Collection” and “Pikachu & Eevee” binders. Both binders will cost 1,550 yen. You can also buy a set of card pages and Pokemon inserts for 598 yen. The “Pikachu & Eevee” binder will only be sold at Pokemon Centers.


It’s likely regular card reveals for SM8 will begin within the next week or two. Stay tuned!

    If you look closely at the Miltank art on the side of the box, you can see Whitney in the background. I wonder if she is also featured as a supporter in the set, and if so, if it does anything similar to the Metagross + Steven's Resolve combination in SM7 / Celestial Storm.

    Emboar/Blacephalon anyone?
  3. Ramo0927 I am a


    Is it me or does Blacephalon look like it's singing the Spongebob theme?

    "I can't hear you!!!"

    "Aye aye, captain!!!"

    All jokes aside, the card is ok. Putting it in Lost Zone sucks, because you don't really have a way to get the energy back. If we get some sort of Supporter that lets us do this, then this card would get an extreme boost, but I heavily doubt it because then the Lost Zone would pretty much be a Discard Pile 2. Overall, yeah it's pretty bad. Why do all the Ultra Beast GX cards(besides the Buzz and Legendaries) have to be so underwhelming???

    Naganadel is cool because you can just use Naga's GX attack and boom you can hit the numbers with Baby Naga. I like the ability too. Not sure if it will see a whole lot of play though.

    Heat Factory is... Well, it's pretty much just a little boosted Scorched Earth but it's a Prism Star card and I hate those. Even if FB isn't affected, they can still put down their own stadium. Because of this, I am gonna have to say its eh.

    But I still have hope though! Just because a few cards are meh doesn't mean the whole set is going to be ba- *Celestial Storm and Forbidden Light Flashbacks*

    Yep nevermind this sets going down a road I don't even want to think about.

    Blacephalon is cool and its GX attack can win games.

    I like seeing the increased lost zone play.
  6. Ashblaze Full Art Supporter Hunter


    I was hoping blacephalon was gonna be good but that attack is risky putting energy into the lost zone, atleast you can be a little even with Lysandre prism and do it to the opponent too, I was hoping the last prism star stadium would be ANY other type, but sadly it’s suppose to be fire cause of blacefalon , I shall never use it but it will shall still be collected all three stadium prism have really nice art,

    THERE BETTER BE A WHITNEY FULL ART I WOULD LOVE IT (technically I would love any full art that gets made it just grows the full art supporter collection) currently that makes two full arts if Whitney becomes official but I still want one more, 7 is a lucky number for full arts for the English set lost thunder, cause at the moment 4 are official being judge, kahili, morty and Mina(god I want Mina) and then the information of elm full art from an old-ish post, I just can’t wait

    Is it a matter of time before Lost Zone Gengar GX gets reprinted? :eek:

    Was there a Whitney card announced? I may have missed it, idea on what it does?

  9. Perfect_Shot Standard sucks, so Ban Expanded


    Wow that Blacephalon sucks. The Naganadel is filler too and the Stadium is barely better than Scorched Earth. Lugia is somewhat playable but many cards have an easier time hitting the same numbers.

    This is looking to be a filler set.
  10. PlatinumDude Aspiring Trainer


    Surprised Head = Mind Blown, Blacephalon’s signature move in the games.

    Anyway, banishing your energies just to attack kind of sucks.

    Heat Factory is pretty much Scorched Earth on steroids but it only works for you.

    Baby Naganadel combos nicely with the GX version’s Stinger to put yourself at 3 prizes.

    These are literally the only cards that have been revealed right now, so I say wait until maybe say 15-20 cards be revealed before making a full judgment.
  12. That Blacephalon is disappointing at best. Looks like the average Blacephalon deck will be similar to Guzzlord. Meme decks anyone?

    Nooo. It'll be harder to import those Lusamine sleeves...

    Heat Factory is playable in all Fire decks. 3 for 1 is very solid.

    And if I read that correctly, the only way to get rid of it is with another stadium, or some obscure pokemon that nobody really plays. Field blower can't nix it. After rotation, stadium use should go down with Parallel leaving (the most popular stadium right now).

    Was hoping Blacephalon was going to be Psychic type. But I guess it makes since to "balances" out the ultra beast line so there's a fire type. Moves aren't bad but lost zone discard hurts though.

    Close to the bottom it gave some information about the other sleeves that have been made and had Whitney on them giving the possible hint that she might be a supporter in this set, If she does become an actual supporter I would love the full art

    Unfortunately, Blacephalon GX isn't very good, and I was hoping that it would be something along the lines of one our creations on the 'Blacephalon GX Predictions' thread. The only card I really like here is Heat Factory Prism, which is an instant 1 of in every Fire deck. Naganadel is....'meh'. It can only charge itself up. (However if it could charge others it would just be insane) and it's attack is just mediocre. I don't see it seeing much play. Lugia GX we've seen before. Overall, a bit of a dissapointing start to 'Explosive Impact'. What I'm really excited for is Celebi Prism....

    Worst GX ever?

    Blacephalon GX has a solid GX attack. It reduces the number of prize cards the deck needs to draw by one and there is a small to negligable chance that it accelerates energy. Mind Blown is not that good since the energies go to the lost zone but it is a decent cleaner move to draw the final prize cards. Can be used as a tech in fire decks similar to Kartana GX for the GX attack mainly.

    Naganadel is a nice tech addition to Naganadel decks. Include some energy switch and it can accelerate to other Ultra Beasts too. The attack is rather nice. It is not a deck on its own but a decent tech addition to Metal Ultra Beast decks.

    Heat Factory Prism is a sure inclusion in Fire decks. It is Scorched Earth on steroids since it draws one more card and cannot be used by the opponent based on the current wording.

    The new sleeves look awesome.

    Blacephalon sucksssss I knew it. Baby Naga is also more or less pointless imo. Oh well.
