MTG March of the Machine Welcome Booster Pack

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. Notably, apart from the token card, none of the cards appearing in the MOM Welcome Booster are featured in the March of the Machine set and some are even from the defunct core sets. The cards retain their original expansion symbol, and some aren't even Standard legal. Instead, the Welcome Booster is more geared towards Commander play.[2] This printing has no effect on their legality.
