5Clash Royale card guide
Witch is a support troop that deals splash damage and keeps summoning skeletons. She hits air and ground and breaks up defenses from behind a tank.
Place Witch behind a tank like Giant, Golem or Knight. Her skeletons distract single-target defenders while she clears swarms from the back with splash damage. On defense she also handles Minion Horde and small troops.
