Green shadow is worst hero of all.
I think only pay2win winter build works on him but so far every other build have not give winrate above 50%.
He also have worst hero spells in this game.

The fact that you don't even know her gender tells me that you don't know enough about the hero to criticize her.
Anyway, try a draw deck with her. You'll change your mind. Smarty has a surprising amount of card draw I've noticed. Bean Counter, Sow Magic Beans, Mayflower, Big Chill, Rescue Radish...
Flourish really helps Sow Magic and Bananasaurus Rex obviously benefits from all this.
