BUS: Trading Card Minmaxing feat. an old promise

[Telna via agora-business]

I transfer Murphy one Legislative card.

I take the promise "Legislative for Justice v2", created by Murphy, from 
the Library and cash it.

For reference:
------------------------------------------------------------------------
"Legislative for Justice v2" created by Murphy

Cashing conditions: The bearer has transferred or granted Murphy one
Legislative Card in the same message as which e cashes this promise, and
has not cashed any other promise between doing so and cashing this
promise, and Murphy has at least one Justice Card.

I transfer one Justice Card to the bearer.
