Trading commanders, exploit or not?

[DonCorazon]

I think the game is most fun when you are a noob and playing with noobs. The more you learn about all the ways to get an edge, the more tainted you become. Its like the ring of power.

I know about a fair amount of stuff but would prefer to play with what I'd call casual players, the ones that are too lazy to take advantage of some of these things like coordinating to trade commanders or farm death gems. Gem generators are so inherently powerful I think they have to be removed. Even a casual player like me can't resist tons of off the charts gem income even with the micro-pain it can bring.
