• This card is the opposite of "Flare Resonator": while this card protects the monster by reducing its ATK, "Flare Resonator" increases the Monster's ATK. "Flare Resonator" is also a Level 3 Fiend-Type monster, whilst "Trust Guardian" is a Level 3 Fairy-Type monster. They were also used in the same episode respectively by the real and the Imposter Jack Atlas, as they resembled the ideas of pure power and trusting friends.
