This is a good card to play when theres a particular opposing character you really want to get rid of this turn, especially if you have something that can take the hits like a champ think Goofy, Knight for a Day or Lumiere, Hotheaded Candelabra
And truth be told, that is a solid game plan
Legalities, Real Cards, and Proxies (The Boring But Important Part) Now the legal mumbo jumbo, but at the end where it belongs
Not only do we get a draw two lose two spell that activates every turn with Decorum Dissertation, there's also Scheming Silvertongue, one of those 'prepared' creatures, which can use Sign in Blood every turn
Also, the removal is pretty bad here since he cut Orzhov Charm to fit Boros Charm
