Hi kind of new to the game here. I got the green/purple starter from a local game store last week (every other product was sold out) and tried playing a locals with it but got destroyed by well built decks. I recently built a better deck online and went on Ebay to buy singles but the shipping and prices for each individual card was kind of insane as I’m used to TCGPlayer optimizing my cart for me lol. I did end up getting the cards I needed but can’t see myself making another deck any time soon if I wanted deck variety for gameplay.

Would I be able to play with proxied cards just at the local level (no store championships) or is that a big no-no in this game?
