To start Heroclix at your comic shop, start by reaching out to the shop owner or staff. They might have beginner-friendly events or be able to guide you. Also, check if they have demo sets available for you to try out and get a feel for the game. Another thing is to join online forums or groups related to Heroclix to learn from experienced players and get tips.
