How does this protect trophies?

Town Hall sits at the center behind multiple defensive layers. Attackers must destroy most of the base to threaten it, making full trophy loss rare.

What league is this best for?

Performs well across Crystal, Master, and Champion League. Defense density is calibrated for the attack power typical at those ranges.

What's the vulnerability?

Heavy air attacks (Electro Dragons, Blimps) can cut across the base. Fill your Clan Castle with air-targeting troops for best results.
