Boom! He impersonated a member of your army, unless you have an actual contract saying he joined you. Last I checked you army is not recognized by the powers that be so impersonation is not yet a crime.
BOOM! The prosecution presents exhibit A: *presents a contract signed 'MorfinBrwny', clearly written in Eris' handwritting* The prosecution rests!
Your narration betrays you! That is your handwriting not my client's! *All the Eris looking people are give citations because I can't tell them apart despite only one of them having popcorn.*
I submit that Eris could not possibly have forged that signature because of her compulsive need to eat paper!
No it doesn't is say you owe me one Blue Eye White Dragon. As a Duel appointed layer I get paid in Yu-gi-oh cards. You were not asked to the witness stand. Also I've seen Eris suppress her compulsion for comedic affect. Not only that but The Narration overrules your conjecture.
