New player that plays online a lot, considering on getting into the physical card scene. I think I found the League in my area that plays the most: any tips on how to jump into the scene? Should I just attend a League night for fun and see how it goes? I know I need damage counters, etc. -- aside from buying sleeves (I hear the Dragon Matte ones are the best), any tips on equipment? The Elite Trainer Boxes feel kinda gambly to me compared to just buying singles.
As someone who made a similar transition in the last year I think attending a pre-release is usually a good time to get acclimated into the environment as everyone only has the pre-release kit to build decks from and the cost of entry is fixed. The next set I believe drops on May 3rd so the pre-release tournaments will probably happen throughout the two weeks before then depending on your shop. If you are attending a pre-release it's a good idea to pick up some sleeves in case you pull some valuable, expensive cards and potentially dice.
If you are looking to go to a league event before mid-april when the next pre-releases will start I think it might be wise to go to the shop and ask the person that knows about Pokémon to help assemble the deck you want to play. This will require you to buy singles, but you will also be guaranteed the cards you want while building some rapport with the people whom work at that shop.
