I can confirm that this method of taking down this TH13 anti 3 star base is the most consistent. I have seen other attempts with Yeti smash and it just doesn’t seem as smooth. I hadn’t known about the zap + quake on defences to guarantee the Royal Champion ability, but it is a handy trick to know.
General Strategy:
- Use zap and quake to soften up the inferno and air defence
- Bring Royal Champion to take out the zapped compartment
- Use your dragons from the bottom
- Use the bat spell to take out the top infernos and defences once your dragons start tanking the splash at the top
