Can cho-manno,revolutionary with pariah aura(on him) be beat?

i have a question regarding the white colour. i`ve played with it, and i had cho-manno, revolutionary( witch cannot be harmed) and an enchantment aura: pariah (witch sais that all the damage goes to the card to witch is equiped) equiped on him. does this mean that the white player is invincible? or how can someone defeat the white player?
