For starters, many of the oldest cards are simply the most powerful cards ever made
If you really want a 1/1 creature for four mana that regenerates in black, I can offer you Darkling Stalker, which outclasses Numai Outcast in every way that counts
If Illvoi Operative was the first spell you cast this turn, the next spell you cast this turn is your second spell
The Commander Legends: Battle for Baldur's Gate Commander Deck From Exile includes a ready-to-play red-green deck with 100 Magic cards (3 traditional foil cards + 97 non-foil cards), a collector's booster sample pack with 2 cards, 1 display commander card as an etched foil card (one copy of the commander card made of cardboard with foil effect on the card edge and in the illustration), 10 double-sided token cards, 1 deck box (with space for 100 cards including sleeves), 1 life counter and 1 rule reference card
So I compiled this handy little guide, with the help of my awesome boyfriend (whos been playing Magic since Revised came out), to help all of us know what sets some of those unidentifiable old cards come from
