Gouki, the once almighty, Gumblar-looping strategy, is not what it used to be, because when lists are frequently running "Double Summon", you know you've fallen low. This link spam deck easily ends on a Link-4, if you don't brick, that is. As your only Starters are "Gouki Suprex", "Super Quantum Red Layer", and Normal Summon + "Fire Flint Lady".
"Gouki the Powerload Ogre" is literally a custom card. It's an unaffected Towers that gets to crazy ATK stats, and can destroy up to 4 cards on the field. All this archetype needs is either a Link-1, which could break the deck entirely, or a better extender from hand, the more reasonable option.
