If a "Code Talker" monster(s) is Special Summoned from the Extra Deck to your field (except during the Damage Step): You can target 1 of those monsters; add 1 Cyberse monster with the same Attribute from your Deck to your hand, also you cannot Special Summon monsters from the Extra Deck for the rest of this turn, except Cyberse monsters (even if this card leaves the field).
