Basically have trophies specific to the clan, and those trophy points can be spent on buffs that affect the roster of 20 members (only the leader can purchase these). Since it affects all the members, I think a timed buff rather than a number of charges would be better.

Or rather than trophies it could simply be some type of points or currency that players earn for the clan. It could be 1 point for every 1,000 energy gained or something as simple as that (perhaps idle energy wouldn't count or something). The buff options could include things similar to the current buffs, although a time limited dark energy might be a little ridiculous. So more along the lines of mindreave, or speed buff. There could even be one that increases attack limits. The prices of these buffs would have to be pretty steep though for obvious reasons. (shouldn't be able to buy one every day, nor should dumper clans be able to get them often, if at all).

This is just a roughly thought out idea but I think it'd be neat and make real clan races more fun/interesting.

I've thought about something along the lines of this for a long time too :P.

Even something like 'Increases buff duration/effectiveness by X%' would be pretty cool for a clan-wide thing.

You could get the points based off the monthly energy score, that way dumper/whore clans wouldn't get a lot and not be able to buy the buffs.

It seems so obvious that I wonder why I didn't think of it myself in the first place. Clan trophies seem like a no brainer. Clan buffs will require some thought. All of this is sadly low priority right now though.
