On my mini the following works well
1 Valkyrie, 1 Wizard, 2 Loons, 3 Gobs
Very high variation in speed, lots of splash units and gobs can kill wiz/archers used in luring before they ever attack
I use something similar for Th10 (2 Valks, 5 gobs) but not sure if its as effective as many people don't even bother luring these days
