The four Bloomburrow Commander decks each contain 10 new cards with the BLC set code. Main Commanders appear as Borderless cards (#0001-0004), while the alternate commanders (#0005-0008) and the rest of the new cards (#0009-0040) appear as normal cards. These cards are permitted in the Commander, Legacy, and Vintage formats. The other cards in these decks (with printed set code BLC and collector numbers #0105-0355) that have been previously printed are legal for play in any format where a card with the same name is permitted.[4]
