The point is you lose to sylvans if you don't tech hard counters. Plus they can easily Ultimate Providence golden fish. The very fact that you need to run negation to stand a chance against Sylvans means your deck is less powerful Vs other meta decks such as masked heroes and Archfiends. It's a big deal. The one deck has a flow on effect that makes a lot of "good decks" ordinary.
It's not a big deal at all, because you can beat them with mill, with dark magician + thousand knives, with HAZY FLAMES, with CA and Vennu, with flying fish, even with kuriboh(s). The fact of the matter is this >>> some of you fuys love to make an issue about everything.0
The OTK might be a problem for this game, no card game with hundreds of cards needs something like OTK, it will 🔥 any game.
BUT SYLVANS ARE NOT A PROBLEM AT ALL, JEEZ THEY AEE EXTREMELY EASY TO BEAT.
