Get Gouki The Master Ogre on the field, use Gouki Finishing Move, and battle away. Easy stuff.
This list in heavily inspired by JaspmanZX, see his list here : https://ygoprodeck.com/deck/gouki-410727.
Best possible combo :
Normal Summon Gouki Suprex, activate effect to Special Summon other Gouki (ex. Gouki Twistcobra).
Link Summon Gouki Jet Ogre, activate Goukis' effects in GY to add Gouki Headbatt and another Gouki (ex. Gouki Riscorpio).
Activate Headbatt effect to Special Summon it discarting Riscorpio.
Link Summon Gouki Thunder Ogre, activate Headbatt effect to add another Gouki (ex. Gouki Iron Claw).
Extra Normal Summon Iron Claw.
Link Summon Apollousa, Bow of the Goddess, activate Iron Claw effect to add Gouki Re-Match.
Activate Re-Match special summoning Riscorpio and another Gouki.
Link Summon Codebreaker Virus Swordsman, activate effect to Special Summon Codebreaker Zero Day and activate Riscorpio effect to add Re-Match.
Link Summon Codebreaker Virus Berserker, activate effect to Special Summon back the Virus Swordsman and Zero Day.
Link Summon them into The Phantom Knights of Rusty Bardiche to the right zone.
Activate Bardiche effect sending The Phantom Knights of Silent Boots to GY and setting The Phantom Knights of Shade Brigandine.
Activate Brigandine summoning itself as a monster.
Link Summon Gouki The Powerload Ogre with Berserker and Brigandine.
Activate Silent Boots effect in GY banishing itself to add Phantom Knights' Fog Blade, set it and End Turn.
Some changes :
- Effect Veiler to bait out interrupts or Battle Phase effects that might prevent the OTK.
- One for One, to get Gouki Guts or Gouki Octostretch from Deck, link it away with Relinquished Anima ((Linkuriboh was the original target) RIP sweet prince), and activate effect to get Gouki Suprex, as the best Normal Summon.
- Reasoning, since almost every Gouki is of a different Level, so it will most likely resolve every time.
- Small World, and use Effect Veiler as a bridge. Only Gouki Guts and Gouki Octostretch cannot be searched, since both Level 1 and 0 DEF.
- Triple Tactics Talent is always nice. This deck is very sensible to interrupts, every single Gouki effect can be Ashed. It helps either recover, or removing an opponent's monster for easier OTK.
- Couple of floodgates (booooo), since you play mostly EARTH Warriors.
- Mekk-Knight Crusadia Avramax in place of Gouki The Blade Ogre, since quite frankly, it might be the worst Gouki Link monster (one man's opinion). Also, Avramax can help get rid of big bads that can only be outed in battle.
- Accesscode Talker can be swapped out for Knightmare Phoenix if you want easier backrow removal. Plus, Accesscode isn't a better beater than Master Ogre, and Phoenix goes into Avramax. I personally picked Accesscode nonetheless because he looks cool.
