Strengths
Anti ground split pathing
Bottom-side entries force troops to split around the side compartments, which makes the Town Hall harder to secure and delays access to the upper Storages.
Mortar loot punishment
Top-side attacks can reach loot faster, but they must stay under Mortar pressure for most of the push.
Upper spring trap bait
Spring Traps between the upper Storages and Archer Towers punish troops trying to move straight through the top compartments.
Unexpected Clan Castle defense
A Valkyrie and Balloon in the Clan Castle are very strong at TH4 and can wipe out careless spam attacks that do not prepare for defending troops.
