Great idea! I'm running small world anyway, which is copies 4-6 of droll. I hope they limit prosperity, as it does not work under it. But Durendals other effect is a nice backup.
I like the idea but you need to draw droll to get the hand loop,while also assuming that the opponent doesn't have called by and that the search he does isn't already when he put a negate(such as imperm, dark ruler,or sending the rank 9 in a mirror match).
