Psychic-Type Xyz Monsters on the field cannot be targeted by Spell/Trap effects. Once per turn: You can discard 1 'Heraldic Beast' monster; add 1 'Heraldry' Spell/Trap Card from your Deck to your hand, except 'Augmented Heraldry'. If you activate this effect, you cannot Normal or Special Summon any monsters for the rest of this turn, except Psychic-Type Xyz Monsters and 'Heraldic Beast' monsters.
