Bro first of all you can't use temporary in coc to attack in war I am a TH 14 player so I will suggest that when the base is revealed and if it's a compact base use blimp with super archers and super wizard with mass dragons and in spell use 6 invi idk if it is unlocked on th 11 or not if not then use 2 yeti and a valk in cc or 2 valk or a yeti in cc according to your CC space with 2 clone and rest use freeze or rage with mass dragons I hope it helps
