Goblin: Generically accessible normal summons will always be a problem, whether it be Gouki or SPYRALs or whatever the fuck else.
Shizuku: The Sky Striker engine is fine, the deck itself is not - I'm cool with people still being able to go Drones Kagari Drones for extra link materials or whatever but the deck itself needs some sort of hit, I don't think getting rid of Shizuku makes the deck completely worthless so I think it kills two birds with one stone.
Invoker: This has always been a broken card which enables really long complicated combos but it's especially true with Gouki since all you need is 2 3's and you're good to go. It wasn't really until the penny dropped with Invoker that Gouki really started dominating, and nowadays people are playing Speedroids and Marauding Captain and even fucking Gilasaurus just to access it.
Scapegoat: Everyone's kinda forgotten about it with Trickstar Sky Striker being slightly less popular but it's still basically a 1 card win button and that's not fair. I don't care for the argument "oh but it allows worse decks to compete", if your deck relies on a sacky unsearchable win button to compete don't play the deck.
Candina: Trickstars should be hit. This is the most efficient way to do so. I'm not prepared to extend them the same sort of leeway as Sky Strikers, the deck is fundamentally annoying and problematic.
Isolde: Card's really good, Gouki or no Gouki. If it doesn't get hit now it will eventually.
Why limit Rivalry of the Warlords and not Gozen Match as well? In fact, why limit either of them?
Indirect Altergeist hit, really. Gozen should eventually move down too, both cards are obnoxious floodgates that tell your opponent they can't play the game.
Why not unlimit apoqliphort towers and demi-limit scout. Let us qliphort players have some fun.
Qliphort players will never have fun. There is nothing less fun than playing Qliphort. Either way, Towers falls into the "cards that can easily move up but I don't care enough" category, and Scout idk about, I'd prefer to keep it at one.
