Th8 War Strategy?

WiVa (Valkyrie, Wizard) is easily the best th8 strategy if you know what base to use it on. Which is a base with poor wall setup.

11 wiz
16 valk
4 wallbreakers, for any Valks that go outside
Some arrangement of 20 troops to kill off cc.
2 heal
1 Rage

Clan castle... Probably balloons to help on cleanup

Make sure your King goes inside. It's essential to the raid. Attack from 2 different spots to make sure valks don't clump. But make the spawn spots a bit close to each other. Clear out some outside buildings before deploying valks, so Valks will go inside the base.

And keep 2 wizards with you until you get 50%, and deploy them off to the side for easy cleanup of any building you have missed. To prevent timing out.
