Idk the name of the attack but it works really well. Ofc u know its golem valk and wiz . im a th9 And i can easily 2 star th9s with golem wizar and valk. My composition is :
The 2 hogz and archer are optional but i suggest you lure out the clan cancel in case there is a dragon or balloon in castle but other than that, than theres no need to lure
anyways
Step 1 : Spread golems to distract defense
Step 2: Send in a few wiz to knock out Outside buildigs (Wall breakers too)
Step 3 Send in a few valks to clear inside building (Usually heal/Rage around this part due to CC troops
Step4: Send in the rest of valk makig sure it goes into the center with the other and than throw in the jumpspell to connect it to townhall with a rage spell in the center to kilk the townhall
Step5. Use barb king and Archer Queen to clear out extra buildings for the 50% if neeeded
It works better if you try it and tweak it yourself but this is pretty much all i do and its pretty amazing what these red heads can do hope it somewhat helps
