GoWiPe level 1,5,1 is pretty weak
Golem 1, Wiz5 and Pekka 1 are pretty weak but since you have pekka 2, you should be able to 2 star that th9. It's pretty easy to get to the core. I like to add 2-4 Valkyrie on bases that have a lot of building close together that fits her attack style.
I'd try 2 golem, 2 pekka, 1 max pekka in cc, 2-4 valks, 6-8 wb, rest wizards. Your goal is to get to core to take townhall.
Oh this is not a game about fair play, lol. Heck, if you let me see your cards playing poker, am I not going to look? I am not the type who will among friends, but in a tournament, you lose not my fault, protect your hand like it's your cash.
If a clan lets anyone join during war, it's like the English letting the Germans in to see their defenses in WWII, lol. Get real, spying is a real part of warfare. We are imitating warfare!!!
