Second Main Phase Trading Company is a one-person Magic: The Gathering singles business in North Texas, built by a longtime Commander player with a background in audit and a conviction that card buying should be transparent enough to survive the seller checking the math.
We buy collections below market value, sell the worthwhile singles, and turn the rest into playable bundled decks. The guides are free and always will be; some pages carry clearly marked affiliate links, which pay us a small commission and never change what we recommend. We say so on any page where that applies.
