!!CALLOUT!!
How about this idea:
It would require two other people besides myself - and a jury of mediator/judges possibly.
Here's how it goes-
The important task of the sole mediator (or group) would name a scan, any scan from any marvel comic and state something about it. The first person between the two debating/ opponents post the scans/on panel feats etc. For instance, the person who chooses says a question something like: " I wanted to see the scan where hulk lifted the mountain or whatever"... then the combatants scurry for the scan ( if they have it of course) - post it, then comprehend the scan and story of whats being discussed. Then on to the next person and next scenario..
SO this is basically an excercise to find out who's got the scans?
This is A callout to one opponent, and a request for a host of judges that call out specific feats.
and one person choosing the scenario for the two combatants to kick it off.
