On 4 war winning streak. I've really hit the sweet spot with Valks and TH10's. got 12 stars on my last 2 wars.
I use 4 healers, 12 valks, 12 wizzies, 8 wb, 2 hogs to lure troops, and the rest archers.
cc has golem giant and poison
3 rage, 1 jump, 1 freeze, and another poison.
level 30 Queen and level 20 King
If you can lure troops out with the 2 hogs, send them to the queen and throw a poison on them. If it looks like your queen is in trouble, rage the healers so they keep the queen alive. After she has taken most of 1 side out deploy CC troops and wbs to destroy first few walls. Send Wizzys to destroy any buildings that can send troops wandering. After Core is Visible send Valks and rage them. Should make quick work of core and enough should survive to destroy the rest of the base. Your queen should also be around to finish cleaning the base.
Have fun.
