Caeleus in Freaks= 15 k
After that happened, other cards would change as well.
Baldy= around 3k
Cassandra= creepy guys into hantai would keep Cass around 2k
Miss Ming= 1-1.5k
Think about it. How many people will pass up Caleus even if he's in a clan with a slight bonus issue. And I mean slight.
But for the actual question, well,
Bob Joby to All Stars- 50 (yep, half off)
Bruce to Skeelz- 200 until the CR rumors start, then 800.
Hula to Jungo- 3.5k
