Why do I feel like I'm always bricking

Hi,

Looking for a bit of insight, but it always feels like I'm getting the worst hands no matter the deck I play. I'm trying to use tournament decks from limitless and I just don't get how some of these players are able to do it honestly. I assume I'm just misplaying a lot, but then there are also situations where I just have like a lumineon start + all evolution pokemon or energies

I like to play Lugia and Dragapult/Thorns, but I'm having a hard time understanding what to do in these situations?
