Where it fails

Core trap laneServiceable
traps sit on one path; a second path avoids themAttacker will: enter from 2 o'clock
Outer storagesServiceable
storages on the outer ring are reachable from the edgeAttacker will: snipe them with a small group first
Clan Castle pullServiceable
the Clan Castle sits where a few troops can lure it outAttacker will: pull the defenders and kill them away from the core

I keep losing to…

Pick the attack that beats you; its route shows on the schematic and alternatives reorder.

How the base works

1The attacker sees spread compartments and a deep Town Hall.
2Expected path: a funnel from 2 or 4 o'clock toward the core.
3Defensive value is spent on wall rings and the long back end.
4It can fail against Electro Dragon spam from 2 o'clock: spread air defenses are far apart on this line.

Deny 3 stars: spends value on wide compartments and the long back end; gives up some Town Hall safety.
