mtg mystery booster cards 2 Booster Pack with playtest cards Mystery Booster/Test cards - MTG

Generous Gift is probably close to an auto-include for me in white decks

Shadows Over Baldur's Gate 1x Grim Hireling 1x Wild-Magic Sorcerer 1x Xorn 1x Prosper, Tome-Bound These four cards encourage you to create a deck with Prosper, Tome-Bound as the Commander, leaning into a dual focus on casting spells from exile and generating treasure tokens as a result

Razorkin Hordecaller Four generic, one red creature Human Clown Berserker 4/4 Uncommon Haste Whenever you attack, create a 1/1 red Gremlin creature token

While Dark Ritual might be the most iconic black spell of all time, fast mana is extremely dangerous to put on a card, especially one that starts in the command zone

Card not found, on the other hand, is the basis for a deck in Modern (its namesake actually) and played in Legacy Storm decks (maybe Vintage as well, I dont know the format enough to say)
