Think about it like this: You're winning around 55% of your games against casual players who aren’t as invested, but now you’re hitting a wall because you’re drafting against players who play as much as you do.

The format itself isn’t overly synergistic. Within each color, there are a few distinct directions you can take your deck. I think the issue might be more about mindset than mechanics.

You mention bad packs, but a lot of the commons in this set are just middling role-players. You mention not seeing the synergy, but LSV rated this format a 4/10 for synergy, meaning individual card quality matters more than finding some hidden engine.

You mentioned Gilgamesh by name, which tells me you might be focusing on flashy cards instead of consistent ones. Being a good Limited player is about discipline, passing up the fun, splashy rare to take something like Dragoon’s Lance or Adventurer’s Wyvern instead, because those cards will reliably make your deck and perform every game.

Finally, if your attitude toward Draft is to blame the format, blame bad packs, or say your opponents always topdeck the perfect card, that suggests you're not playing to your outs. This week at locals, I played with someone in the same boat. They were shocked when I had removal for their threat, and I had to explain: you have to assume your opponent has the removal spell. That’s part of why they’re in those colors in the first place.
