The scenario Grimwalker mentioned: defending the Deadly challenge with 2 characters, one of which was "touched by Dany." Depending on the order, you could lose just the one, or you could lose both.
The situation could come up fairly often if Dany has Deadly and marks "awesome character," I would probably choose to defend with awesome character and chump - in hopes of winning the challenge and trading the death of chump for awesome character. If Dany's controller then mucks around with challenge resolution and I end up losing. In that situation, depending on who FP is, there is at least a chance of keeping the chump.
That's more or less exactly what happened. He overcommitted with two defenders, I burned him with some non-terminal stuff, enough to ensure I still won, and I didn't want to let his 4-cost unique go Deadly-Moribund before Daenerys' ability landed. If the big guy is Dany-Moribund, then the other character has to be sacrificed to Deadly, and that's the way I wanted it to be.
My opponent had two objections: He wasn't convinced Dany's effect would resolve in the Passive step (since it was created by a Response) and he was under the impression that even if it were, that keywords resolved before other passives.
