LF: Bunnie and Flora!
I would like to trade her for either Diana or Marshal! 
How do you even trade villagers? How do you even know they will go to the town?
When a villager's in boxes, he/she can be claimed to someone by wifi / local multiplayer / streetpass. Trading villagers is more specific than that, but generally it's just letting someone come over to get your villager, and vice versa.
