Supreme Lord Shapeshifter

Martin didn't know why he was still thinking. But some kind of voice talked to him in his mind It said to choose to "Silver Soul Controller"

"I choose "Silver Soul Controller".

While I'd like to agree on the "gamemasters" and I also like the uniqueness of the sound of its abilities...

It is also, of the 2, the lesser of them in terms of what Martin usually likes to do.

Not to mention that the "gamemaster" is probably based around unique abilities and is probably not nearly as powerful in offensive or defensive maneuvers. I see him becoming the type to rely heavily on fooling enemies, trapping them, or using illusions at the best.

While that is powerful it's not his style from what we've seen and isn't nearly as useful as the "Silver Soul Controller" in my opinion. "
