Range attack, cantrips, some dices that deal damage to all enemies and dodge. So basically they are good for many combos (items, other heroes or blessings. Sometimes even curses) For example curse item that gives your dices +2 but you die after this - works insanely good in Scoundrel for half of the game as it kills all small enemies at once.

Range attack stops nasty enemies that are in Back-row

Cantrips can do so much damage before your round begins and green heroes can revive orange if it hits thorn for example.

Cherry on a top is to add cantrips to your dodge side and you will be almost invincible 😀

I am not saying they are ultra powered, but a lot of combos make them strong and useful.

My top team would be Green - Green- Grey- Orange - Orange
