Cytorrak's bands are be on the short list of things that actually could stop Cain.
Doc could probably cut Juggy off from his Crimson Cosmos energy supply if he wanted to also.
He could also float him in a ball no leverage like he does in the Defenders when the Hulk gets unruly.
Or he could bend space/time into and endless M.C. Escher type maze where Cain can walk forward all he wants but still never get anywhere.
Really, and contest other than arm wrestling Strange wins. Heck, if he bothered to study it, he could probably invoke Cytorrak to gain Juggernaut-type powers himself. It's not his usual style, but he could certainly do it. Imagine Jugg's might with Strange's Mantis-league hand to hand skills. Surprise Cain!
