Okay so I have encountered a problem with the Mandarin Mountain Toss feat.
I can't provide all the scans because they'd be too many, I recommend you just read the issue, it is from Iron Man Vol 1 275. But essentially,
Rhodey is implied to not have survived the strike Mandarin gave him. So how did he come back you may ask? A page before
some reality warping shenanigans happened, so I really think the writers are implying we chalk it up to that somehow resurrecting Jim.
And to note by the way, this is Mandarin after he had mastered the rings, so he is essentially unscaleable to his prior incarnations (I am working on a Mandarin CRT and essentially this dude goes through ALOT of power ups), and thus far in my research he hasn't fought Iron Man in any relevant way.
So I think the feat may be unusable, sorry.
