Since the witch is going to become completely useless as a means for tripping traps, I think we need a troop designed specifically for that.
Id say a skeleton horde but skellies don't trip traps come update so maybe a rat horde or something. Each unit deploys 4 rats that sniff out traps. Each rat are one shot killed and attack no buildings or defense. They can take up 2 spaces in your troop space. They spring spring traps but are not effected by them. Bombs and giant bombs will blow them up though. They out run skellies who will chase them all around until rat dies. They're whole purpose is to find bombs so once they find one they sit beside it and blow up. If all bombs are destroyed they can then attack buildings or defenses but are really weak.
