If a card is summoned (Quickeffect): Special summon this card from your hand. If this card is special summoned: Special summon up to 4 Level 4 or lower Monster from your Deck but negate their effects for the rest of this turn. You can only use each previous effect once per turn. A Synchro Monster that gets summoned with this card as material gets the additional effect: "This card is unaffected by cardeffects except its own" You can only use this effect once per Duel.
