What if the sliver Queen survived the Rathi Overlay when her spark ignited. She was lost in a strange place, driven insane by trauma and the loss of her hive. She spends ages growing the hive until she's sane enough to look for a way home, and starts planeswalking. It's painstakingly slow, since she starts from 0 every time she reaches a new strange place and she has to rebuild her hive mind every time, but eventually she finds her way to a plane that feels like home. But Phyrexia is gone, so she winds up on New Phyrexia instead.

She arrives by chance at the same time as Karn is returning to try a diplomatic solution to the Phyrexian problem. Also coinciding, Innistrad's moon has collided with the plane, releasing Emrakul, whose siblings join in. I designed a good deal but probably won't finish it on account of everything that's happened since, so enjoy the cards I did design for MTG Infinity War.
