If it's hard to lure your CC then the best combo would be 2 wizards and 17 archers. The archers take ages and/or a lot of attacking troops to lure and if they don't finish the job then they will get fried by the wizards. Too many wizards or high space troops like dragons are too easy to lure quickly and dispose of on the edge. Dragons will only be a problem for the very noobiest of attackers.
