In our just-ended Birthright game, we ran across a DoMT about 10th-12th level.
No one died. The UMD rogue's cohort got Voided, and we eventually were able to get him back...like, 16th level or so.
My cohort/secondary drew a "No realm income this turn" card, and then a "Double Realm Income This Turn" card for his two draws. Given he didn't *have* a realm, that was no big deal. He then promptly sat down and fainted.
The elf mage's cohort drew the Outsider Enmity card. Given that my tiefling rogue was right there, I was asking if said cohort had uncanny dodge, and if he could beat my 25 initiative.

Sadly, DM ruled I wasn't the one who was the guy's enemy. Pity.
My character first signed over his possessions to the priest-paladin (who drew 0 cards), with the understanding he'd get them back, but he got a +2 Inh. bonus to Int, and defeated the next creature he fought for an extra level, but lost 10 points of bloodline, which hurt like hell.
Later on, we drew from a variant deck in Return to White Plume Mtn. My secondary got drawn to the center of the earth, then hit with a curse on him whenever he traveled by ocean*, a d8 slam attack, and a +10 Str -4 Int +1LA racial adjustment. He...lost that draw.
