I have to say I am quite pleased recently with the quality of decks I have been encountering online. I am playing against better opponents with better decks than in the prior weeks, and that's really good to see.
Recently I encountered a Mewtwo Trainerlock deck, and it was quite an exciting game. Each time I would knock out a Mew Prime he would Twins for another one and it was a tough battle all the way to the end.
Initially my opponent let me knock out his starting Relicanth so that he could play Twins. He put Muk and Jumpluff in the lost zone, and twice used sludge drag when he could have used mass attack. Each time I was able to retreat the poisoned pokemon and knock out the Mew with Yanmega.
later I encountered a Samurott / Feraligatr deck, unfortunately my deck came out slow and let him get two samurott's down, and I couldn't keep them tied up. I would poison and confuse one with Roserade, and he would retreat one, rain dance the water energy onto the other and just keep pounding.
Don't be put off by your opponent's win count. I started looking for games with my Zekrom deck, and my first two opponents conceded within 10 seconds - but only because they didn't want to play against that kind of deck
This is perfectly fine. I don't see many people playing in the Practice Match PvP area, everyone seems to head right for the Ranked Games, Which means if you don't have a top level deck, you still look for ranked games, but concede quickly to decks you can't compete against.
Hope all your games are good ones.
