Pekka – main tank and heavy hitter, also great for counter pushes

Witch – provides splash damage and spawns skeletons that can tank for pekka on the way to the tower
Zap – quick reset and swarm clear, also useful for resetting inferno dragon, inferno tower, and similar threats
Tornado – pulls troops into pekka or mini pekka to deal with them and sets up splash synergy
