Why people don't like to use trumps for Rebma

[Drascus]

Yeah, I love Trump for that.  I'm playing in an Amber game as well as running one right now, and my PC is a Trump artist.  It's just got so much potential for amazing stuff.

It ruins the floor every time you use it :

ROFLMAO!

I love it!

Good discussion on Trumps all, I like the failsafe idea.
kinda like writer's/GM initiative. Sometimes certain things fit in the story that don't have o be precedent setting. This could lead to more argumentative rule-mongering players, but situation dictates.
I could see the mind/psyche of the trumper & trumpee having something to do with velocity breakdown to a certain extent.
In one of my other games, Champions (3rd edition rules!, Hardcover 4th messed it all up) I played a speester, and within the couple decades of playing him, he did eventually visit Amber, but that time he was a bit primal himself, and in a  climactic scene he was the 'bullet' through the trump so to speak. Every power is dangerous in creative hands.
