Thanks for agreeing to look into it. For reference when you follow this up, the sets that miss out the Hirelings & Cheating rule are:
- Super Munchkin Sidekicks
- Munchkin Axe Cop Allies
- Munchkin Bites! Minions
- Munchkin Fu Mooks
- Munchkin Impossible Hirelings (the sacrifice rule isn't listed for these either)
- Star Munchkin Sidekicks
The sets that do list the rule are:
- Munchkin (4,5 & 8) Hirelings
- Munchkin Conan Comrades
- The Good, The Bad and The Munchkin Sidekicks
I also just discovered that you can change the sex of a Sidekick in TGtBatM with any card that would change a munchkin's sex. Hadn't noticed that particular set-specific rule before either...
