Don't think the tamable are out yet. Might have better luck once they are for this year. Most people that have em already are probably inactive or aren't selling.
I can change your lucky charm in my 525/520/100/100 nightmare or in a 825/809/105/475 dragon think about it
The ones in the instances I have killed are NON casters... so I hope he makes them casters if they can be tamed again...
