Our options are therefore as follows: Azorius v Jund: Will, Scion of Peace & Ikra Shidiqi, the Usurper + Kediss, Emberclaw Familiar Rakdos v Bant: Judith, Carnage Connoisseur & Shanna, Purifying Blade Selesnya v Grixis: Trelasarra, Moon Dancer & Solkanar the Swamp King Boros v Sultai: Firesong and Sunspeaker & Zimone and Dina Golgari v Jeskai: Beledros Witherbloom & The Archimandrite Okay, there should be six, but if you can find an oppositional pair in Dimir and Naya that can both be reasonably called a life gain deck, go for it

These are cards that generally retail for between $0.25 and $1.00, but are only purchased for $0.05 or $0.10 (many buylist count played commons and uncommons valued at $0.05 or under as bulk) This last part is important: generally buylists are not a great place to sell cards of lower rarities unless they are high end tournament staples (cards like Path to Exile or Serum Visions) or unless the are literally bulk (selling a $0.20 card that no one wants and has little potential to increase in the future for $0.05 is a great deal, considering bulk rates are $0.005 per)
