What matters most in a TH10 layout
Inferno Towers define Town Hall 10. Whether they are placed close to the Town Hall or split towards the edges decides how attackers plan their entry, and multi-target versus single-target settings change which armies struggle. Check that the Infernos and X-Bows are not all reachable with one push or one set of spells.
Many TH10 attacks still rely on Hog Riders, Bowlers or air armies. Layouts that spread the air defenses and keep Giant Bomb spots unpredictable tend to make these attacks less reliable.
