Konami has finally confirmed the release date for the upcoming Doom of Dimensions expansion pack. Slated for release on the 26th of September, this set will also come with a new wave of Gouki support.
Gouki Mashin Suprex

Level 4 EARTH Warrior Tuner Effect Monster
You can only use the (1)st and (2)nd effect of this card's name each once per turn.
(1) You can reveal this card and 1 other “Gouki” monster in your hand; Special Summon both, but you cannot Special Summon while you control either of those monsters, except “Gouki” monsters.
(2) If this card is sent from the field to the GY: You can add 1 “Gouki” card from your Deck to your hand, except “Gouki Mashin Suprex”.
It looks like the original Gouki Suprex is getting a bigger brother. Mashin Suprex sports the same card advantage package that most of the main deck Gouki monsters have once sent from the field to the graveyard.
What differentiates Mashin from the original Suprex is that Mashin preserves the normal summon of the turn. Unfortunately, Mashin Suprex and its partner’s continued existence on the field locks the controlling player to Gouki monsters.
Thankfully, Gouki can easily go into one of its many Link monsters to remove the said lock if needed. As a tuner, Mashin Suprex does open lines to synchro summoning depending on what’s available.
Gouki The Tyrant Ogre

1 “Gouki” Link Monster + 1 Warrior, Dinosaur, or Cyberse monster
You can only use the (1)st effect of this card’s name once per turn.
(1) If this card is Fusion Summoned: You can target cards on the field, up to the total Link Ratings of the “Gouki” Link Monsters used as material; destroy them. If you used a Link-3 or higher monster as material, those cards cannot be activated in response to this effect’s activation.
(2) If this card battles, your opponent cannot activate card or effects until the end of the Damage Step.
A strange step for the archetype, Gouki The Tyrant Ogre offers a pretty good board-breaking tool if you can meet its needed parameters. Targeted destruction while denying quick effect activation is a type of disruption that Gouki greatly needs for modern Yu-Gi-Oh!
As for its needed materials, the Gouki archetype has more than enough Link and warrior monsters in its roster to easily fulfill the bare minimum summon conditions as well as its on-summon effect.
Wrapping up Tyrant Ogre’s package is a pretty standard battle protection. It's in flavor, given Gouki’s theme of parodying wrestlers, but other than that, it’s a little lackluster.
Gouki Dragon Ogre

You can only use the (1)st and (2)nd effect of this card’s name each once per turn.
(1) If this card is Synchro Summoned: You can add 1 “Gouki” Spell from your Deck to your hand.
(2) If this card is sent to the GY: You can target 1 EARTH monster you control; add 1 “Gouki” monster with lower ATK from your GY to your hand, also, while the targeted monster is face-up on your field, your opponent’s monsters can only target that monster for attacks.
Expanding the extra deck roster, Gouki Dragon Ogre is the archetype’s debut into the synchro scene.
Thanks to Mashin Suprex’s capabilities, Dragon Ogre can easily be reached with just two cards in hand right away. From there, the controlling player can search out what is possibly Gouki’s most powerful Spell card, Gouki Re-Match.
After that, a player already has a good amount of resources to go into further extra deck plays.
Re-Match can bring back the original two bodies used to summon Dragon Ogre. Even Dragon Ogre itself can bring back another Gouki monster as long as its recursion parameter is followed.
This monster is an extremely powerful extension tool that the archetype needs to keep up with more modern deck designs.
Gouki Sheik Ogre

2 “Gouki” monsters
You can only use the (1)st and (2)nd effect of this card’s name each once per turn.
(1) If a “Gouki” monster(s) is added from the Deck to your hand, except by drawing it: You can Special Summon any number of “Gouki” monsters from your hand with different Levels from each other, but you cannot Special Summon while you control any of those face-up monsters, except “Gouki” monsters.
(2) During your Main Phase: You can Fusion Summon 1 “Gouki” Fusion Monster from your Extra Deck, using monsters from your hand or field as material.
Gouki Sheik Ogre is the in-archetype answer to accessing Gouki The Tyrant Ogre. As a Link-2 monster, however, a player might need to bring out another Gouki Link monster if they hope to take advantage of Tyrant Ogre’s effect nullification.
Sheik Ogre also parallels Mashin Suprex’s special summon lock with its first effect. That said, it’s a small price to pay for all the potential bodies Sheik Ogre can pull from the hand.
It's a simple card for what it does, but simplicity always has a place in Yu-Gi-Oh!
Gouki Fighting Spirit

You can only activate 1 card with this card’s name per turn. You can only use the 2nd effect of this card’s name once per turn.
(1) When this card is resolved, you can Special Summon 1 Level 4 or lower EARTH monster (Warrior, Dinosaur, or Cyberse) from your hand in Defense Position.
(2) You can Tribute 1 Link-3 or higher “Gouki” monster; Special Summon 1 “Dinowrestler” or “G Golem” monster from your Deck or Extra Deck.
Probably the strangest card revealed, Gouki Fighting Spirit ties the Gouki archetype to Dinowrestlers and G Golem. It’s a pretty nice reference to the Yu-Gi-Oh! VRAINS animated series, even if it is a confusing one to port to the TCG.
The varied first effect of this card is welcome but not exactly necessary due to the Gouki archetype having enough tools in their arsenal to bring out extra bodies.
As for its second effect, there may be a few possible targets when reaching outside of the Gouki archetype. G Golem Crystal Heart can be brought in as an extra body for Link climbing.
G Golem Invalid Dolmens gives protection to co-linked monsters while potentially turning off the face-up monsters on your opponent’s side of the field.
G Golem Dignified Trilithon acts as an omni-negate shield for your Link monsters, and if you need targeted destruction, Dinowrestler Giga Spinosavate or Dinowrestler Pankratops can be used.
The list of usable targets outside of the Gouki extra deck monsters is pretty slim. Fighting Spirit definitely adds to the archetype’s versatility. At the moment, however, it may not be able to answer Gouki’s current lack of durability against modern hand traps.
