Help with TH 10 War attack strategies

I'm really struggling with wars at TH 10 so far. I can almost always get the 2 star, but am rarely ever close to the 3 star. I am looking for some advice and want to try some new things as far as troop and spell composition. I have seen that having high level heroes is key, and have seen a lot of people doing queen walks at this level. I have been constantly upgrading heroes, but is there anything effective I can do for war in the months that it is going to take to get my heroes to 30+? Any advice concerning this is greatly appreciated 👍. Some of my troop levels are Queen (21), King (20), Golem (5), Bowlers (2), Valks (5), Wizard (6), Loons (6), Freeze (4), Heal (6), Rage (5). Also, my pekka is currently going to level 4 and am upgrading healer to max next so I can begin to queen walk.

I had problems when I first got to th10 also. The strat I use now is valks w aq walk w great success is 2 golems, 1 is in cc, 10 valks, 1 pekka, 4 healers, 5 wall breakers, and wiz and minions for fill. 2 jump 3 heal w poison for cc troops. I have had great success with this start.

Bo witch any day any time. Just youtube it. Comp is around 1 golem 8 witches and rest bowlers. 2 jump 2 rage 1 heal/freeze 2 poison.. Use witches on edges to funnel the golem heroes and bowlers into core.

I've had great success using Queen Walk with LaLoon and baby dragons.
Your heroes are very low so QW is out of the question for high to max TH10s.

I'd say variations of LaLoon or BoWitch is your best bet.
I have a video and detailed explanation when I take down an 89k TH10,5 as a TH10 with air here:
