Protect Your Creatures
A great way to prep for a pre-release or drafting in general is to know what cards can affect your board. Here’s a list of commons that’ll be game changers or have a board affect that you’ll see more often. Take note of card type and mana cost. Dont forget to practice sealed and practice drafting using the Deck Drafer app.
Ghostly Wings can be used to bounce creatures if needed.
Don't forget that, although it's a rare occurance, madness enabled enchantments can come in at instant speed.
Think of this as a 4 drop that can kill one of your blockers before the combat phase.
These are the cards that can destroy your creatures or surprise you in combat. It helps to memorize the mana costs, because if your opponent plays those colors, they will likely have these cards in their deck.
Good luck in your prep for the new set!
