The good news is, structure based deck arent that strong ( except for Hero lol, and dont forget stratos) compared to nowadays meta. You can beat them pretty much with any KoG worthy deck or rogue deck. We dont have any case just like how ancient gear controlled the meta ages ago.
The last meta defined ex deck was desperado. Really hated this period. Sartorius was everywhere. They were even in 2019 yugioh finals. After that Sartorius skills got a nice nerf and invokes hit the scene making desperado deck obsolete.
Check the top 5 KCGT decks. 1 of them is Shiranui (expensive backrow, but f2p achieveable with proper gems management) and another one is Lunalight. Means f2p can reach such achievement if one has time to dedicate.
That’s how we all know you’re full of crap. You don’t get KoG with pure F2P decks, you sneak in cards that you have to pay for, and just call it F2P. Actually investing funds into DL promotes the game, unlike like you who losses all the time hiding behind kiteroid. F2Ps do nothing as always.
