Take something related to mtg or mtgpq. Whether it be lore or an actual card.
Then ruin it.
I’m going to leave a post I left in another thread as an example:
Kamigawa So there were humans and spirits and snakes and stuff. They fought and somebody won.
Mirrodin: So there was a planet full of metal, but then it got Phyrexianized. Just oil and sadness now…
Ravnica: Buildings man…there’s lots of them here. Sometimes there’s people in the buildings, sometimes they’re outside…next to the buildings. Lots and lots of buildings.
Theros: Gods don’t like each other and everybody is an enchantment.
Come to Azor’s ornate floor tile emporium! You’ll never want to leave!*
*your ability to leave may or may not be connected to said ornate floor tile which you may or may not ever see or gain ownership of. Shut up I’m a giant kitty with wings, and I’ll give my floor tile to whoever I want! You’re not the boss of me! Also I ruined hundreds of other worlds and made them build statues of me.
