Lore
From The Bazaar site:
"A shrewd Jaballian who dreams of life as a tycoon, Pygmalien leverages his knowledge of investments, economics, and income generation to get a leg up in The Bazaar...at his opponent's expense, of course."
Playstyle
While Pygmalien does have ways to play aggressively (he can literally beat you up with a Yo-Yo), he's typically seen as the slow and steady hero.
This is because of his economic capabilities that allow him to scale his income to levels the other heroes can't get anywhere close to.
If you manage Pyg's finances correctly, he can become virtually invincible and even win battles without a single weapon - he can simply outlast his enemies and let the timed sandstorm kill them.
How to Unlock Pygmalien
Pygmalien must be unlocked using Gems. If you get a Founder's Pack you'll have enough Gems to buy both him and Dooley.
If not, you'll need to unlock Pygmalien by earning Gems from the ranked ladder.
