Basically take a famous quote (if unknown just site it as unknown) and use that for the flavor text. Then make a card that makes sense to have that quote as the flavor text.

For example. First one I got when I googled famous quotes was this. " Life is like riding a bicycle. To keep your balance, you must keep moving." —Albert Einstein

So now a card.

Recuperating W
Instant
Return to the battlefield target creature that was sent to the graveyard from the battlefield this turn that wasn't sacrificed.
Buyback 2W
"Life is like riding a bicycle. To keep your balance, you must keep moving." — Albert Einstein

My quote I try to make random. Use any quotes appropriate for this forum and not too long. Doesn't need to be random.

Martyrs' Legacy 1WW
Enchantment
Creatures you control get +1/+1 for each legendary creature card in your graveyard.
"The life of the dead is placed in the memory of the living."
—Cicero
