lab transfigured gem - add 'transform a trans to a new trans of the same type'

My friend has failed 10 times in a row to make an ice nova of frostbolts.
As there are 2 trans on this gem, the chance of this would be 1/1024... but even that is unacceptable. If 1024 people want to play this skill, one of them will fail that many times in a row. That's just insane.
Having to run lab that many times is not intended gameplay, and not fun gameplay.
