Who are the most powerful pretenders?

Edi said:
He's available to the Tuatha, Eriu and Man. So a restricted pretender, hence not as all around powerful as the enchantress which is available for all nations. The enchantress also has one more item slot that can be used to wear a booster. Mounted units do not have foot slots for items.

He also has the advantage of being stealthy, which is a big boon for human-mage pretenders, since IIRC it protects you 100% from normal assassination attempts.

...Although I believe he normally only produces 1 gem; I think CBM ups the rate to two gems.
