The Crimson Vow Welcome Boosters are fixed samplers, given away for free to provide potential new players a taste of what Magic: The Gathering offers and guide them on the first steps of their journey with the game. Welcome Boosters were refreshed for this set in English only, and only were available in North America. Other languages received a Midnight Hunt version.
The Welcome Booster contains ten cards. Each Welcome Booster is exactly the same and contains a sample of legendary creatures, planeswalkers, rares, foils, showcase cards, and more. Some cards appear in the VOW Welcome Booster but do not appear in the Crimson Vow set. They retain their original expansion symbol. This printing has no effect on their legality.
The package also contains three double-sided advertisement or helper cards from a series numbered 1-24 (marked with an A) that contain tips on how to get started, find stores, and learn more about the game. In addition, it contains a MTG Arena code card for the Wild Wizardry deck in MTG Arena. However these Welcome Boosters do not give the players any tips on learning to play the game, and since Wizards of the Coast have removed learn to play decks, it has become harder for new players to get in to the paper game.
