Okay Magician's Items work like this.

Handcuffs force two people to use their roles on each other.
Cloak Protects the Magician from night kills.
Sword Box has 50/50 chance of killing someone, or doing nothing.

Night 1:
Barack Obama->No Action
Taft investigate->Bill Clinton
John Adams Protect-> John Adams
George Bush Sr. Kill->

Night 2:
John Adams Protect-> Reagan
Taft Investigate-> Reagan
FDR kill-> Reagan
Barack sword box-> Thomas Jefferson

Night 3:
John Adams Protect-> Reagan
Taft Investigate-> FDR
Barack Obama Handcuffs-> Reagan and Taft (Taft ends up investigating Reagan instead of FDR because of this)
George W. Bush Sr. Kill-> Reagan

People used roles very well!
