As of 3pm today your local FLGS (mines The Hobbit Hole) will be running pre-release events for the Core Set 2020. Or they are allowed to run them I should say.
It also means your FLGS is able to sell booster boxes with the buy-a-box promo.
Don’t forget to take some sleeves with you to the pre-release and some lands. Although your FLGS will provide lands for you to use. Which means I most likely will forget both.
I hope you get a great promo card and some great pulls in your pre-release kit, and have a great time playing MtG with the new cards.
