Trading commanders, exploit or not?

[Dimaz]

Micah, I agree with you, but the point is that it has to be explicitly specified in game house rules, because otherwise it gives unfair advantage to players who exploit these tricks. So even if I dislike gem burning very much, when I see that someone in a game where I play goes that way, I will certainly use it myself (if house rules say nothing about it). However, as it's really sometimes tough to say if it was abusing or not, such rules may become too strict. So I see no good solution here.
