What are the rarest figures in the MU line?

[blotertom]

Out of the 3.75 Marvel Universe figures released so far, which ones do you guys

consider to be the rarest? I know there are obvious ones like the SDCC figures,

but what else stands out among the sea of Iron Man peg warmers that are out there?

I would personally be amazed to find the following in stores:
Blade
The Comic 2 pack that accidentally included Deadpool

I'd like to hear your opinions on figures that are rare online too, so let me know

what you think.
