yea then if u didnt know helen specialty then lemme say u………..helen removes buffs of the enemies (extra attack,shield,shit etc) and removes frm her team also that means (burn,poison,lower attack, etc) so if freya puts a shield then helen will remove the shield frm ur hero and takes all ur buffs and put on our heroes with also heals the hero……..
So practically helen is better
