Ok, so this is the third tourney that I've joined that resulted in a player having a deck made almost entirely of GX and EX Pokémon who spent about 3 minutes on their first turn and one shot a high HP Pokémon on their second... So am I being put up against good players, or are they hacking and spoiling the fun for us? They always seem to start with the same basic loadout as well.
正真正銘 is correct above. However, math is really hard, so I'll take this time to explain from a TCG perspective.
"The same basic loadout" is what we call staples - cards that should be in every competitive deck. That's your Tapu Lele GX, Sycamore, Ultra Ball, etc. You know, the good stuff. These are what make decks successful.
Besides that, what you played in the log you posted is quite typical of Buzzwole decks. They are designed to set up incredibly quickly and start one-shotting things on their 2nd turn if possible.
The problem was not your opponent getting lucky. Your opponent played two incredibly standard turns. Decks in 2018 want to tear through their deck ASAP to get as many cards as possible. The small amount of luck was pulling that Float with N, but I'm not sure how many he ran. The issue was you not having a Supporter to start the game. No, Lana doesn't count. It doesn't do anything. Trust me here. The reason you lost, at base value, was that your opponent saw
25 of his 60 cards (42%), while you saw essentially 8 (13%). He also just had a better deck than you, but that's a separate issue.
In short, it is neither bad luck nor hacking. If you end your first turn with only a single Basic in play in 2018, you need more draw support. If you'd like to post your list, I can look at it. Just looking over the log, I'd start by replacing every Lana with Professor Sycamore if you can.
Edit: to expand a bit - While Versus attempts to pair you against players of similar skill, Tournaments on the TCGO do NOT. They don't care how good you are, you can get paired against anyone else. I recommend staying out of non-theme tournaments until you have a competitive deck. And I'm sorry if this came off as blunt.
