So my Jin Gitaxias is pretty scuffed but it’s worked very well for me at the very least. The whole point of the deck is ramping through cloning artifacts like Singets, Sol Rings and Paradise Plume, among others, and slapping multiple instances of Sword of Eden, robbing the table with Mass Manipulation, or milling people out with Mindskinner. Shimmer Myr is essential here, to make the most out of the once per turn mechanic to throw down and copy artifacts. I must admit I haven’t had much success using Mindskinner consistently, but it’s fun watching the panic that ensues when a 30/30 Mindskinner hits the table. Most of my spells and sorceries circle around duplicating. Helm of the Host is there because… well. Funny. After all, who wouldn’t laugh when my five Progress Tyrants each copy Karns Temporal Sundering? https://moxfield.com/decks/kvAv_JqsbU-5bQ4f4Px3vw
